The reciter: Abu Bakr ibn Abi Shaybah, Abu Kuraib, and Ishaq ibn Ibrahim all narrated from Waki', and Abu Bakr said: Waki' narrated to us from Zakariyya ibn Ishaq, who said: Yahya ibn Abdullah ibn Sa'if narrated to me from Abu Ma'bad from Ibn Abbas from Mu'adh ibn Jabal, and Abu Bakr said: Waki' sometimes said from Ibn Abbas that Mu'adh said:
The Messenger of Allah sent me (as a governor of Yemen) and (at the time of departure) instructed me thus: You will soon find yourself in a community one among the people of the Book, so first call them to testify that there is no god but Allah, that I (Muhammad) am the messenger of Allah, and if they accept this, then tell them Allah has enjoined upon them five prayers during the day and the night and if they accept it, then tell them that Allah has made Zakat obligatory for them that it should be collected from the rich and distributed among the poor, and if they agree to it don't pick up (as a share of Zakat) the best of their wealths. Beware of the supplication of the oppressed for there is no barrier between him and Allah.
بعثني رسول الله صلى الله عليه وسلم ، قال : إنك تأتي قوما من أهل الكتاب ، فادعهم إلى شهادة أن لا إله إلا الله وأني رسول الله ، فإن هم أطاعوا لذلك ، فأعلمهم أن الله افترض عليهم خمس صلوات في كل يوم وليلة ، فإن هم أطاعوا لذلك ، فأعلمهم أن الله افترض عليهم صدقة تؤخذ من أغنيائهم فترد في فقرائهم ، فإن هم أطاعوا لذلك ، فإياك وكرائم أموالهم ، واتق دعوة المظلوم ، فإنه ليس بينها وبين الله حجاب
