حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ كَانَ إِذَا أَتَاهُ السَّائِلُ أَوْ صَاحِبُ الْحَاجَةِ قَالَ " اشْفَعُوا فَلْتُؤْجَرُوا، وَلْيَقْضِ اللَّهُ عَلَى لِسَانِ رَسُولِهِ مَا شَاءَ ".
