Umayyah ibn Bistam al-‘Ayshi narrated to us, Yazid ibn Zuray‘ narrated to us, Rawh — and he is Ibn al-Qasim — narrated to us, from Isma‘il ibn Umayyah, from Yahya ibn ‘Abdullah ibn Sayfi, from Abu Ma‘bad, from Ibn ‘Abbas, that when the Messenger of Allah (peace and blessings be upon him) sent Mu‘adh to Yemen, he said: "You will come upon a people who are People of the Book. Let the first thing you call them to be the worship of Allah, the Mighty and Majestic. When they come to know Allah, then inform them that Allah has obligated upon them five prayers in their day and night. When they do that, then inform them that Allah has obligated upon them charity (zakat), taken from their wealthy and returned to their poor. When they obey in that, then take it from them, and beware of taking the choicest of their wealth."
