Sayyiduna Imran bin Husayn (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "O Fatimah, get up and be present at your sacrifice, for with the very first drop of its blood every sin you have committed will be forgiven you. And say: 'Indeed, my prayer, my sacrifice, my living and my dying are all for Allah, the Lord of the worlds. He has no partner; with this I have been commanded, and I am of the Muslims.'" Sayyiduna Imran (may Allah be pleased with him) said: "O Messenger of Allah, is this specifically for you and the people of your household - for you are worthy of it - or is it for the Muslims in general?" He (peace and blessings be upon him) said: "Rather, it is for the Muslims in general."
