صَحِيحُ مُسْلِمٍ
Sahih Muslim 1014 a
The Book of Zakat
Acceptance of charity that comes from good (Tayyib) earnings, and the growth thereof
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ سَعِيدِ بْنِ يَسَارٍ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم مَا تَصَدَّقَ أَحَدٌ بِصَدَقَةٍ مِنْ طَيِّبٍ - وَلاَ يَقْبَلُ اللَّهُ إِلاَّ الطَّيِّبَ - إِلاَّ أَخَذَهَا الرَّحْمَنُ بِيَمِينِهِ وَإِنْ كَانَتْ تَمْرَةً فَتَرْبُو فِي كَفِّ الرَّحْمَنِ حَتَّى تَكُونَ أَعْظَمَ مِنَ الْجَبَلِ كَمَا يُرَبِّي أَحَدُكُمْ فَلُوَّهُ أَوْ فَصِيلَهُ .
Abu Huraira reported Allah's Messenger (ﷺ) as saying: If anyone gives as Sadaqa the equivalent of a date from that (earning) earned honestly, for Allah accepts that which is lawful, the Lord would accept it with His Right Hand, and even if it is a date, it would foster in the Hand of the lord, as one of you fosters his colt, till it becomes bigger than a mountain.
