Sunan Abi Dawud, 1584

Narrated Ibn 'Abbas:said When the Messenger of Allah(ﷺ) sent Mu’adh to Yemen, he said to him You are going to a people who are people of the book. So call them to bear witness that there is no diety but Allah, and that I am the Messenger of Allah. If they obey you in this respect, tell them that Allah has prescribed five prayers on them every day and night. If they obey you in this regard tell them that Allah has prescribed sadaqah(zakat) on their property and returned it to their poor. If they obey you in this respect, do not take the best of their property. Beware of the curse of the oppressed, for there is no curtain between it and Allah

Rapporté par Ibn 'Abbas رضي الله عنه : Lorsque le Messager d’Allah ﷺ a envoyé Mu’adh au Yémen, il lui a dit : « Tu vas rencontrer un peuple des gens du Livre. Invite-les à témoigner qu’il n’y a de divinité qu’Allah et que je suis le Messager d’Allah. S’ils acceptent cela, informe-les qu’Allah leur a prescrit cinq prières chaque jour et chaque nuit. S’ils acceptent, dis-leur qu’Allah a prescrit la zakat sur leurs biens, à redistribuer à leurs pauvres. S’ils acceptent, ne prends pas le meilleur de leurs biens. Prends garde à l’invocation de l’opprimé, car il n’y a pas de voile entre elle et Allah. »
