Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said that the Prophet (peace and blessings be upon him) said: "A Muslim is the brother of a Muslim: he does not wrong him, nor does he disgrace him. Whoever fulfils his brother's need, Allah fulfils his need; whoever relieves a Muslim of a hardship, Allah will relieve him of a hardship on the Day of Resurrection; and whoever conceals the faults of another Muslim, Allah will conceal his faults on the Day of Resurrection."

He said: No. He said: Then throw away the whip, and do not tear open a veil that Allah has drawn.

Maysarah said: A mother and her son came to Sayyiduna Ali (may Allah be pleased with him). She said: He has killed my husband. The son said: My slave had intercourse with my mother. Sayyiduna Ali (may Allah be pleased with him) said: You have both come to ruin. If you are truthful, we will kill him; and if your son is truthful, we will stone you. Then Sayyiduna Ali (may Allah be pleased with him) went to the prayer, and the boy said to his mother: What do you think, that I should be killed or that you should be stoned? So the two of them left. When he (may Allah be pleased with him) finished the prayer and asked about them, he was told that they had gone.
