كتاب الزكاة
Read the English translation first, with the original Arabic directly underneath.
Abu Huraiarh said:
"The Messenger of Allah said: None gives charity from (wealth earned from) a good source - and Allah does not accept anything but that which is good - but the Most Merciful takes it in His right hand, even if it is a date, and it tended in the hand of the Most Merciful until it becomes grater than a mountain, just as one of you tends his foal or camel calf."' (Shih)
مَا تَصَدَّقَ أَحَدٌ بِصَدَقَةٍ مِنْ طَيِّبٍ وَلاَ يَقْبَلُ اللَّهُ عَزَّ وَجَلَّ إِلاَّ الطَّيِّبَ إِلاَّ أَخَذَهَا الرَّحْمَنُ عَزَّ وَجَلَّ بِيَمِينِهِ وَإِنْ كَانَتْ تَمْرَةً فَتَرْبُو فِي كَفِّ الرَّحْمَنِ حَتَّى تَكُونَ أَعْظَمَ مِنَ الْجَبَلِ كَمَا يُرَبِّي أَحَدُكُمْ فَلُوَّهُ أَوْ فَصِيلَهُ
