Sayyiduna Imran bin Husayn (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "O Fatimah, be present beside your sacrifice when it is slaughtered, for with the very first drop of its blood all the sins you have committed will be forgiven, and say: 'Indeed, my prayer, my sacrifice, my living and my dying are for Allah, Lord of the worlds' [Surah al-An'am: 162-163]." I asked: O Messenger of Allah, is this for you and for the people of your household exclusively, or for the Muslims in general as well? He (peace and blessings be upon him) said: "Rather, it is for the Muslims in general as well."
(b) It is reported from Sayyiduna Abu Musa (may Allah be pleased with him) that he used to order his daughters to slaughter their sacrifices with their own hands.
