Abu al-Haytham Dukhayn (may Allah have mercy on him) said: We had some neighbours who used to drink wine. I forbade them, but they did not stop. So I said to Sayyiduna Uqbah bin Amir (may Allah be pleased with him): "Our neighbours drink wine; I have forbidden them but they have not stopped, and I am going to call the police on them." He said: "Leave them, woe to you! I heard the Messenger of Allah (peace and blessings be upon him) say: 'Whoever sees a fault of a Muslim and conceals it, it is as though he brought back to life a baby girl buried alive from her grave.'"
