the Messenger of Allah said: "None gives charity from Tayyib - and Allah does not accept but Tayyib - but that Ar-Rahman accepts it with His Right (Hand). Even if it is a date, it is nurtured in the Hand of Ar-Rahman until it is greater than a mountain, just as one of you nurtures his foal or young camel."
قَالَ رَسُولُ اللَّهِ ﷺ مَا تَصَدَّقَ أَحَدٌ بِصَدَقَةٍ مِنْ طَيِّبٍ وَلاَ يَقْبَلُ اللَّهُ إِلاَّ الطَّيِّبَ إِلاَّ أَخَذَهَا الرَّحْمَنُ بِيَمِينِهِ وَإِنْ كَانَتْ تَمْرَةً تَرْبُو فِي كَفِّ الرَّحْمَنِ حَتَّى تَكُونَ أَعْظَمَ مِنَ الْجَبَلِ كَمَا يُرَبِّي أَحَدُكُمْ فَلُوَّهُ أَوْ فَصِيلَهُ قَالَ وَفِي الْبَابِ عَنْ عَائِشَةَ وَعَدِيِّ بْنِ حَاتِمٍ وَأَنَسٍ وَعَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى وَحَارِثَةَ بْنِ وَهْبٍ وَعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ وَبُرَيْدَةَ
