Even if that thing is true (and correct)?" The Messenger of Allah (peace and blessings be upon him) said: "If you have said something untrue (about someone), then that is slander (not backbiting)."

The Prophet (peace and blessings of Allah be upon him) said: "You have backbitten him." The companions said: O Messenger of Allah! We only mentioned (the fault) that is present in him.

One of them said to his companion: "This servant is imitating the sleep of your Prophet." And in another narration: "He is imitating the sleep of your household." Both of them woke him up and said: "Go to the Messenger of Allah (peace and blessings be upon him) and say to him that Abu Bakr and Umar send you greetings of peace and they are asking you for some curry (side dish)." The Prophet (peace and blessings be upon him) said: "Convey my greetings to both of them and inform them that you both have already eaten curry." Abu Bakr and Umar became anxious upon hearing this and went to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah! We sent (so-and-so) to you to get curry, and you said that we have already eaten curry. (By Allah), what curry have we eaten?" He said: "The flesh of your brother. By Him in Whose hand is my soul, I can see his flesh between your teeth." Sayyiduna Abu Bakr and Umar (may Allah be pleased with them both) said: "Pray for forgiveness for us." The Prophet (peace and blessings be upon him) said: "It is your servant who should pray for forgiveness for you."

Whenever I tried to get close to him, the companions would stop me. The Prophet (peace and blessings of Allah be upon him) said, "Let him be." I got so close to him that the neck of his mount touched the neck of my mount. I said, "O Messenger of Allah! Tell me of a deed that will keep me away from Allah's punishment and admit me to Paradise." The Prophet (peace and blessings of Allah be upon him) said: "(1) Worship Allah and do not associate anything with Him. (2) Establish the obligatory prayers. (3) Pay the zakat. (4) Fast in the month of Ramadan. (5) Perform Hajj and Umrah. (6) Also, examine yourself: whatever you like for people to do to you, do the same to them, and whatever you dislike for them to do to you, do not do that to them."
