عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ ﷺ: “مَنْ تَصَدَّقَ بِعَدْلِ تَمْرَةٍ مِنْ كَسْبٍ طَيِّبٍ، وَلَا يَقْبَلُ اللَّهُ إِلَّا الطَّيِّبَ، وَإِنَّ اللَّهَ يَتَقَبَّلُهَا بِيَمِينِهِ، ثُمَّ يُرَبِّيهَا لصاحبها، كَمَا يُرَبِّي أَحَدُكُمْ فَلُوَّهُ، حَتَّى تَكُونَ مِثْلَ الْجَبَلِ”.
Hazrat Abu Hurairah (ra) narrated that Allah’s Messenger (sa) said, “Whoever gives in charity even the equivalent of a single date from pure earnings – and Allah accepts only what is pure – Allah accepts it with His right hand, then nurtures it for its giver just as one of you raises his foal, until it becomes like a mountain.”
