It is obligatory that the sacrifice be made at Mina and if it is not possible because of the rush there and Mina is not able to accommodate all the pilgrims the sacrifice may be made at Wadi Muhassar. If, by delaying the sacrifice, it becomes possible for the pilgrim to make the sacrifice in Mina he may delay it upto the thirteenth of Dhil Hijjah.
Rule 379: As a matter of caution, the sacrifice must be made on the day of Idd but if the pilgrim forgets or omits to do so for other cause or ignorance of the rule, then it is obligatory to do so by the l3th of Dhil Hijjah but if the cause continues to subsist, it may be delayed to the end af Dhil Hijjah. As a matter of caution, the sacrifice must not be made at night except by those who are fearful. Rule 380: Each pilgrim is obliged to make one sacrifice.
Rule 381: It is obligatory that the animal of sacrifice be either a camel, a cow or a goat. It is not permissible to sacrifice a camel unless it has reached the age of five years and has entered the sixth. If it is a cow or a goat it must have completed two years and, as a matter of caution, entered the third and if it is a sheep unless it has completed the seventh month and entered the eighth. As a matter of caution, it must have completed one year and entered the second.
If after the sacrifice, the pilgrim learns that the age of the animal was less than the required, the sacrifice is not proper and will have to be made again. It is also necessary that all the parts of the animal be sound; it must not be blind, lame, without ears or with damaged horns, etc. Indeed it is apparent that it should not be castrated (unless another is not found), weak, sick, very old or diseased in both testicles.
There is no objection if its ears are injured or perforated although, as a matter of caution, they must be clear of such defects. As a matter of recommended caution, it must not have been born without a tail or horns. Rule 382: If a pilgrim purchases for sacrifice a sound animal without any deformity and pays its price and later discovers that it has a defect, it will be sufficient as a sacrifice.
Rule 383: If possible, the conditions for sacrifice discussed above should be fulfilled but if a condition cannot be fulfilled, a pilgrim should fulfil as many of them as possible. Rule 384: If an animal of sacrifice is slaughtered in the belief that it is fat but it transpires that it is weak, it will still be sufiicient and another need not be purchased and slaughtered.
