DIFFERENT VIEWS OF MARAJE
1. Unity of Horizon If the moon is sighted at a place, it
establishes the first of the month for all areas sharing the same night.
2. Multiplicity of Horizons If the moon is sighted at a place, it
establishes the first of the month for all areas sharing the same horizon.
RULINGS
Q: When is the first of the month?
A: It is the day following the evening when you are reasonably certain of the
presence of the crescent on the horizon of the place where the Mukallaf resides, in a manner in which it is visible to the naked
eye.
ASTRONOMICALFACTS
The moon is not a light source.
It can be seen because it reflects sunlight.
A new crescent appears every 29 or 30 days, never fewer
or more.
ASTRONOMICAL FACTS
The Moon is circling the earth in a counter clockwise elliptical
orbit
This allows us to see the different phases of the moon.
ASTRONOMICAL FACTS
The exact time when the moon passes between the center of the
earth and the center of the sun, called "conjunction" can be
precisely calculated, exactly as the moment of sunrise or sunset
can be determined precisely.
ASTRONOMICAL FACTS
This moment of time is also called "New Moon" and is a black
invisible moon, which will be in over 32 hours of disappearance.
CRESCENT SIGHTING CRITERIA
Based on data collected from late 1980s by the World Federation,
a criteria has been developed for calculating the likelihood of
crescent visibility.
This criteria has been continuously improved by the data
collected for crescent observation.
A very effective tool to calculate ahead of time, whether the
moon can be sighted.
CRITERION
ELONGATIONAfter the moon comes out of conjunction it takes some time for it to get away from the sun such that the crescent can be seen from the earth.
In 1931 the French Astronomer, André Danjon, suggested that scientifically it was not possible for the crescent to be seen when the angle of separation (elongation) is less than 7°, regardless of what the age of the crescent is and regardless of any favourable observing circumstances that may exist.
Our data suggests that this angle of separation (elongation) between the sun and the moon must be at least 9.7° for the crescent to be sighted with the naked eye.
ALTITUDE
At sunset the altitude of the moon above the horizon must be high enough above the glare of the sun for the crescent to be sighted.
A young crescent is usually sighted when the sun has dropped at least 5° below the horizon, which is about 20 minutes after sunset.
Therefore the moonset time has to be more than 20 minutes after the sunset time.
CRITERION
CRESCENT AGE
Our records show that with a naked eye, while no crescent can be seen before it is 16 hours old, it may still be up to 23 hours old, or more in certain seasons, before it is visible.
CRITERION
ELONGATION – More than 9.7˚
ALTITUDE – More than 5˚
CRESCENT AGE – More than 16 Hours.

PROOF OF CRESCENT SIGHTING
When one personally sees it.
By certainty or conviction.
When TWO Aadil (righteous) male persons stand
witness to the fact that they saw the crescent.
When 30 days of a lunar month are completed.
AGHA’S RULING
“If the moon is sighted in the East, it also applies to the West as long as the latitude of the two locations are not greatly further away from one another”
AGHA’S RULING
“If the new moon is sighted in a city, it is sufficient for other cities, provided they share the same horizon, in the sense that the actual sighting in the first city would necessarily be followed with the sighting in the second city if there were no barriers like clouds, fog, mountains etc”
AGHA’S RULING

“If the new moon is sighted in a city, it is sufficient for other cities, provided they share the same horizon, in the sense that the actual sighting in the first city would necessarily be followed with the sighting in the second city if there were no barriers like clouds, fog, mountains etc”
AGHA’S RULING - SUMMARY
Can follow sighting in the East if:
1) Distinct Possibility of Sighting Exists in West ( i.e. in your own city)
2) Cities in East are not far apart on the latitude lines (i.e. follow the moon path which changes on monthly basis.)
COMMON QUESTIONS???
Q: (According to calculations by astronomers for the new crescent of Shawwal 1424, there is possibility of sighting in South Africa on Tuesday night.) This may result in differences between the followers of the Marja who believes in sharing the night principle and the one who does not. How do you suggest we resolve these differences?
A: There is no need to resolve the differences. Everyone has to act according to the rulings of his or her Marja.
COMMON QUESTIONS???
Q: Can we rely on predictions of Astronomers?
1741. The first day of a month will not be proved by the prediction made by the astronomers. However, if a person derives full satisfaction and certitude from their findings, he should act accordingly.
(From Taudheeul Masaael of Ayatullah Seestani)
COMMON QUESTIONS???
Q: If a crescent on the second night is high and large, is that an indication that we may have erred in the beginning of the month?
1742. * If the moon is high up in the sky, or sets late, it is not an indication that the previous night was the first night of the month. Similarly, if there is a halo round it, it is not a proof that the new moon appeared in the previous night. (From Taudheeul Masaael of Ayatullah Seestani)
COMMON QUESTIONS???
Q: What about confirmed reports of sighting to the Eastern areas of our locality?
1744. * If the first day of a month is proved in a city, it is also proved in other cities if they are united in their horizon. And the meaning of having a common horizon in this matter is that if new moon was sighted in a city, there would be a distinct possibility of sighting it in the other cities, if there were no impediments, like, the clouds etc. (From Taudheeul Masaael of Ayatullah Seestani)
COMMON QUESTIONS???
Q: Is the declaration of a Mujtahid binding on his followers?
1740. The 1st day of any month will not be proved by the verdict of a Mujtahed and it is better to observe precaution.
(From Taudheeul Masaael of Ayatullah Seestani)
RULING
Question Ruling #1) In your esteemed opinion, the
expressions like “man shahida minkum…” in the Qur’ãn or “sum li ’r-ru’ya…” in hadīth has mawdū‘iyyat or tarīqiyyat for the beginning of the Islamic month?
ANSWERSighting has been taken as a ‘tariqiyyah’ – means to ascertain the manifestation of the crescent in the horizon such that it can be sighted with the naked eye, if there were no impediments like clouds, etc. If another method – other than sighting – could be used to ascertain the presence of the Crescent in the manner specified, it would suffice.
The Report of Sighting on 31st August 2008 in DetroIt
“Some respected mu’mineen of Detroit (including a member of the CrescentCommittee) acquired information from an observatory in Michigan about the possibilityof sighting the crescent in Detroit and were told that there was a very weak possibility of
sighting the crescent in that area.Nonetheless, they decided to go for moon sighting so that, at the least, they could
report that they went out to look for the crescent but didn’t see it. S. Haider Bahar al-Uloom used various computer soft wares to find the exact location of the sun and the
moon at sunset in Detroit. Then they went to the 7th floor of a building which had a goodview towards the sunset direction.
Between 7:48 and 7:52, the crescent was sighted first by Br. Aws Asfar, then by SyedBaqir al-Kashmiri and then by Sayyid Haider Bahar al-Uloom. They were initially
surprised to see what they were not expecting. So they turned away and then again settheir eyes towards that direction. Again Br. Aws saw it four times, S. al-Kashmiri saw it
three times and S. Bahar al-Uloom saw it once more. Then they all three drew what theyhad soon on papers and compared their sketches with one another. This is how they
became sure of having seen the crescent.”

Yallop’s response last yearPortsmouth, UK, on Wednesday 1 October 2008 the lag time will be 13minutes and q = +0.044 B, so the crescent moon will be visible on that day.At best time, q = + 0.061 B.)A team will be at a vantage point on Portisdown, and assuming idealconditions, we are considering the following:1) Before the sunset: the crescent will be over 57 hours old with an elongationof over 28 degrees.
2) At sunset: this will be at 18:33 when the moon will be 1.3 degrees above the horizon.
3) At 'best time': this will be at 18:39 when the moon altitude will be 0.6 degrees above the horizon.
4) When the sun is 5 degrees below the horizon: sighting will not be possible asthis will occur at 19;00 when the moon will have already set.
In your experience what are our chances of successfully seeing the crescentBy naked eye?
Response from Yallop:
“With a moon of that age I would expect that you could see it in broad daylight, not just twilight.Certainly I would expect it to be visible with binoculars by that time. Itis not easy to spot, but once you have seen it you would wonder how youcould have missed it. When my grandchildren were very young and I waspushing them around in a push chair, they would often spot it and tell me.”
This year, we again asked both experts as to the possibility of sighting the moon before sunset on Sunday 20 September 2009. Their responses were not adequate to determine whether the crescent could be sighted before sunset. The replies of both of the experts are pasted below:
Mohammad Shawkat Odeh. Islamic Crescents' Observation Project (ICOP when presented with the scenario for this year “Where as for Shawwal, according to my experience, I believe the crescent can be seen about 15 minutes before sunset by optical aid, but I doubt that it could be seen by naked eye.”
Response from Professor Yallop:“You know and I know that you cannot say anything for certain when it comes to making an observation with the unaided eye in the worst part of the sky down by the horizon close to the sun.”
