It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever does not concern himself with the affairs of the Muslims is not one of them; and whoever does not begin his morning and evening as a sincere well-wisher of Allah, His Messenger, His Book, the imam of the Muslims and the Muslims in general, is not one of them."
This hadith is not narrated from Sayyiduna Hudhayfah (may Allah be pleased with him) except with this chain, and Abdullah bin Abi Ja'far al-Razi (may Allah have mercy on him) is alone in narrating it.
