Abu Huraira:
حَدَّثَنَا مُحَمَّدُ بْنُ سِنَانٍ ، حَدَّثَنَا فُلَيْحٌ ، حَدَّثَنَا هِلاَلٌ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَمْرَةَ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَا أُعْطِيكُمْ وَلاَ أَمْنَعُكُمْ، أَنَا قَاسِمٌ أَضَعُ حَيْثُ أُمِرْتُ " .
Allah's Messenger (ﷺ) said, "Neither do I give you (anything) nor withhold (anything) from you, but I am just a distributor (i.e. Qasim), and I give as I am ordered."
