Every adult Muslim, male or female, who owns 613.35 grams of silver or its equivalent in money, personal ornaments, stock-in-trade or any other form of wealth which is surplus to his basic needs, is under an obligation to offer a Qurbani. Each adult member of a family who owns the above mentioned amount must perform his own Qurbani separately. If the husband owns the required quantity, but the wife does not, the Qurbani obligatory on the husband only and vice-versa. If both of them have the prescribed amount of wealth, both should perform Qurbani separately.
If the adult children live with their parents, Qurbani is obligatory on each one of them possessing the prescribed amount. The Qurbani offered by a husband for himself does not fulfil the obligation of his wife, nor can the Qurbani offered by a father discharge his son or daughter from their obligation. Each one of them should care for his own.
However, if a husband or a father, apart from offering his own Qurbani, gives another Qurbani on behalf of his wife or his son, he can do so with their permission.
No Alternate for Qurbani
Some people think that instead of offering a Qurbani they should give its amount to some poor people as charity. This attitude is totally wrong. Actually, there are different forms of worship obligatory on Muslims. Each one of them has its own importance and none of them can stand for the other. It is not permissible for a Muslim to perform salah instead of fasting in Ramadan, nor is it permissible for him to give some charity instead of observing the obligatory Salah. Similarly, Qurbani is an independent form of worship and this obligation cannot be discharged by spending money in charity.
However, if somebody, out of his ignorance or negligence, could not offer Qurbani on the three prescribed days (10th, 1lth and 12th Zulhijjah) then, in that case only, he can give the price of a Qurbani as sadaqah to those entitled to receive Zakah. But during the days of Qurbani no Sadaqah can discharge the obligation.
The Time of Qurbani
Qurbani can only be performed during the three days of Eid, namely the 10th, Ilth and 12th of Zulhijjah. It is only in these days that slaughtering of an animal is recognized as an act of worship. No Qurbani can be performed in any other days of the year.
Although Qurbani is permissible on each of the three aforesaid days, yet it is preferable to perform it on the first day i.e. the 10th of Zulhijjah.
No Qurbani is allowed before the Eid prayer is over. However, in small villages where the Eid prayer is not to be performed, Qurbani can be offered' any time after the break of dawn on the 10th of Zulhijjah.
Qurbani can also be performed in the two nights following the Eid day, but it is more advisable to perform it during daytime.
