Musnad Ahmad Hadith 17447

Dukhain, who was the scribe of Uqbah (may Allah be pleased with him), narrates that once I said to Uqbah (may Allah be pleased with him) that our neighbors drink alcohol, I am going to call the police so that they may come and arrest them. Uqbah (may Allah be pleased with him) said, do not do so, rather advise them and warn them. The scribe did so, but they did not desist. So Dukhain again came to Uqbah (may Allah be pleased with him) and said, I forbade them but they did not desist, and now I will surely call the police. Uqbah (may Allah be pleased with him) said, Alas! Do not do so, because I heard the Prophet (ﷺ) say that whoever conceals the faults of a Muslim, it is as if he saves a girl buried alive.
