It is narrated from Sayyiduna Jabir bin Samurah (may Allah be pleased with him) that whenever food was brought to the Prophet (peace and blessings be upon him) and he (peace and blessings be upon him) ate from it, he would send what was left of it to Abu Ayyub (may Allah be pleased with him), and Abu Ayyub (may Allah be pleased with him) would look for the marks of the fingers of the Prophet (peace and blessings be upon him) and place his own fingers where he saw the marks of the fingers of the Prophet (peace and blessings be upon him). One day a dish was brought to the Messenger of Allah (peace and blessings be upon him) and he (peace and blessings be upon him) found the smell of garlic in it, so he (peace and blessings be upon him) did not eat from it, and he sent it to Abu Ayyub (may Allah be pleased with him). Abu Ayyub (may Allah be pleased with him) did not find the mark of the fingers of the Prophet (peace and blessings be upon him) in it, so he said: O Messenger of Allah! I did not see the mark of your fingers in it? He (peace and blessings be upon him) said: "I perceived the smell of garlic in it." He said: You sent me something that you do not eat yourself? He (peace and blessings be upon him) said: "The angel comes to me."
