It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him), he says that it was said to him: Some of our neighbors drink alcohol, should we seize them and hand them over (to the police)? He said: No, because I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever sees a fault (in a Muslim) and then conceals it... al-hadith."
