عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ يَبْلُغُ بِهِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((يَقُولُ اللَّهُ عَزَّ وَجَلَّ: يَا ابْنَ آدَمَ! اَنْفِقْ أَنْفِقْ عَلَيْكَ، وَقَالَ: يَمِينُ اللَّهِ مَلَأَى سَحَّائُ، لَا يَغِيضُهَا شَيْءٌ اللَّيْلَ وَالنَّهَارَ))
It is narrated from Sayyiduna Abu Hurairah that the Messenger of Allah, peace and blessings be upon him, stated: Allah Almighty said: O son of Adam! Spend (in My way), I will spend on you. Then the Prophet, peace and blessings be upon him, said: Allah’s right hand is full and always giving, and nothing spent during the night and day can diminish it.
