It is narrated from Sayyiduna Abu Mas’ud (may Allah be pleased with him), he says: The Messenger of Allah (peace and blessings be upon him) delivered a sermon to us, he (peace and blessings be upon him) praised and glorified Allah and said: Surely there are hypocrites among you. As I mention each one by name, he should stand up. O so-and-so! You stand up. O so-and-so! You also stand up. In this way, the Prophet (peace and blessings be upon him) mentioned the names of thirty-six men, and then said: There are hypocrites among you, so fear Allah Almighty. Sayyiduna Umar passed by a man whose name had been mentioned; he had covered himself with a cloth. Sayyiduna Umar (may Allah be pleased with him) recognized him, and asked him: What has happened to you? He narrated to him the hadith of the Messenger of Allah (peace and blessings be upon him). He (Umar) said: May distance be for you for the rest of the days.
