Sahih al-Bukhari, 4347

Rapporté par Ibn `Abbas : Le Messager d’Allah (ﷺ) a dit à Mu`adh bin Jabal lorsqu’il l’a envoyé au Yémen : « Tu vas aller vers un peuple du Livre, et quand tu arriveras chez eux, invite-les à témoigner qu’il n’y a de divinité digne d’être adorée qu’Allah et que Muhammad est Son Messager. S’ils acceptent cela, informe-les qu’Allah leur a prescrit cinq prières à accomplir chaque jour et chaque nuit. S’ils acceptent cela, dis-leur qu’Allah leur a ordonné de donner la Sadaqa (c’est-à-dire la zakat) à prélever sur les riches parmi eux pour la donner aux pauvres parmi eux. S’ils acceptent cela, fais attention ! Ne prends pas leurs meilleurs biens (comme Zakat) et crains l’invocation de la personne opprimée, car il n’y a pas de barrière entre sa prière et Allah. »

Narrated Ibn `Abbas:Allah's Messenger (ﷺ) said to Mu`adh bin Jabal when he sent him to Yemen, "You will come to the people of Scripture, and when you reach them, invite them to testify that none has the right to be worshipped except Allah and that Muhammad is His Apostle. And if they obey you in that, then tell them that Allah has enjoined on them five prayers to be performed every day and night. And if they obey you in that, then tell them that Allah has enjoined on them Sadaqa (i.e. Zakat) to be taken from the rich amongst them and given to the poor amongst them. And if they obey you in that, then be cautious! Don't take their best properties (as Zakat) and be afraid of the curse of an oppressed person as there is no screen between his invocation and Allah
