Sahih Muslim Book - 12, Hadith - 2343

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا يَعْقُوبُ - يَعْنِى ابْنَ عَبْدِ الرَّحْمَنِ الْقَارِىَّ - عَنْ سُهَيْلٍ عَنْ أَبِيهِ عَنْ أَبِى هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « لاَ يَتَصَدَّقُ أَحَدٌ بِتَمْرَةٍ مِنْ كَسْبٍ طَيِّبٍ إِلاَّ أَخَذَهَا اللَّهُ بِيَمِينِهِ فَيُرَبِّيهَا كَمَا يُرَبِّى أَحَدُكُمْ فَلُوَّهُ أَوْ قَلُوصَهُ حَتَّى تَكُونَ مِثْلَ الْجَبَلِ أَوْ أَعْظَمَ ».

It was narrated from Abu Hurairah that Messenger of Allah (SAW) has said: “No one gives in charity a date earned from a good (Tayyib) source, but Allah takes it in His right hand and tends it as one of you tends his colt or young she-camel, until it becomes like a mountain, or a bigger.”
