Sa’ib bin Yazid (may Allah have mercy on him) says that I set out from Madinah to Makkah with Sa’d bin Malik (may Allah be pleased with him), and I did not hear him narrate even a single hadith from the Prophet (peace and blessings be upon him), until we returned. Hammad said that (he did so) out of reverence and the gravity of narrating from the Prophet (peace and blessings be upon him), and our condition is such that we narrate such and such (hadiths) between ourselves and the Prophet (peace and blessings be upon him) and we waste them.
