It is narrated from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) arrived in Madinah Munawwarah, the Ansar drew lots among themselves to determine who would be the first to host the Messenger of Allah (peace and blessings be upon him). The name of Sayyiduna Abu Ayyub (may Allah be pleased with him) was drawn, so he hosted the Messenger of Allah (peace and blessings be upon him) at his home. Then, whenever food was presented as a gift to the Messenger of Allah (peace and blessings be upon him), Sayyiduna Abu Ayyub (may Allah be pleased with him) would also be given a share. One day, when Sayyiduna Abu Ayyub (may Allah be pleased with him) entered, there was a bowl containing onions. He asked: What is this? The people replied: The Messenger of Allah (peace and blessings be upon him) has sent it. He went to the Noble Prophet (peace and blessings be upon him) and asked: O Messenger of Allah! Why did you not eat from this bowl? The Prophet (peace and blessings be upon him) replied: I saw onions in it. I asked: Are they not lawful for us? The Prophet (peace and blessings be upon him) replied: Why not, you may eat them, but there comes to me (in the form of revelation and angels) that which does not come to you.
