ALLAH INCREASES YOUR CHARITY H 563 "If a person gives in charity - even as little as a date from his lawfully gained earnings and Allah only accepts that which is pure - Allah accepts it with His Right Hand and nurtures it for him as one of you would tend a calf, until it becomes like a mountain." R 563 Bukhari and Muslim with a chain up to Abu Hurairah who related that the Prophet, praise and peace be upon him, said this.
560- وعنه ، قَالَ : قَالَ رسول الله صلى الله عليه وآله وسلم : "مَنْ تَصَدَّقَ بعَدلِ تَمْرَةٍ مِنْ كَسْبٍ طَيِّبٍ ، وَلاَ يَقْبَلُ اللهُ إِلاَّ الطَّيبَ ، فَإنَّ اللهَ يَقْبَلُهَا بِيَمِينِهِ ، ثُمَّ يُرَبِّيهَا لِصَاحِبِهَا كَمَا يُرَبِّي أحَدُكُمْ فَلُوَّهُ حَتَّى تَكُونَ مِثْلَ الجَبَلِ" متفقٌ عَلَيْهِ . " الفَلُوُّ" بفتح الفاء وضم اللام وتشديد الواو ، ويقال أيضاً : بكسر الفاء وإسكان اللام وتخفيف الواو : وَهُوَ المُهْرُ .
