Abu Musa reported that when any needy (person) came to Allah's Messenger (ﷺ) with a need he commanded him to his Companions, saying:Make a recommendation for him, and you would get the reward. Allah, however, gives the verdict through the tongue of His Apostle what He likes most.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، وَحَفْصُ بْنُ غِيَاثٍ، عَنْ بُرَيْدِ، بْنِ عَبْدِ اللَّهِ عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا أَتَاهُ طَالِبُ حَاجَةٍ أَقْبَلَ عَلَى جُلَسَائِهِ فَقَالَ " اشْفَعُوا فَلْتُؤْجَرُوا وَلْيَقْضِ اللَّهُ عَلَى لِسَانِ نَبِيِّهِ مَا أَحَبَّ " .
