It is narrated from Sayyiduna Umayr bin Habib bin Khumashah (may Allah be pleased with him), who had reached the time of the Prophet (peace and blessings be upon him) at the age of puberty, that he counselled his sons, saying: "My sons! Beware of sitting with fools, for sitting with them is a disease. Whoever is forbearing with a fool is happy, and whoever answers him back regrets it. And whoever is not content with a little of the ill-treatment a fool brings (that is, does not tolerate it) is in the end compelled to be content with (to endure) a great deal of it. And when one of you intends to enjoin what is right or forbid what is wrong, let him prepare himself to be patient with harm and have firm trust in the reward from Allah, the Mighty and Majestic, for whoever trusts in the reward from Allah, the touch of harm does not hurt him."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Ja'far al-Khatmi (may Allah have mercy on him) except Hammad bin Salamah (may Allah have mercy on him), and Ibn Aishah (may Allah have mercy on him) is alone in narrating it."
