Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) passed by some grain (a heap of food), and he (peace and blessings be upon him) put his hand into it, then said: "Whoever deceives us is not one of us."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Mutarrif except Sawwar bin Mus'ab, and this hadith is narrated from al-Bara' (may Allah be pleased with him) only with this chain."
