O son of Adam, spend. I will spend on you. The right hand of Allah is full and overflowing and in nothing would diminish it, by overspending day and night.  

النَّبِيَّ ﷺ قَالَ قَالَ اللَّهُ تَبَارَكَ وَتَعَالَى يَا ابْنَ آدَمَ أَنْفِقْ أُنْفِقْ عَلَيْكَ وَقَالَ يَمِينُ اللَّهِ مَلأَى وَقَالَ ابْنُ نُمَيْرٍ مَلآنُ سَحَّاءُ لاَ يَغِيضُهَا شَىْءٌ اللَّيْلَ وَالنَّهَارَ  

" Spend, I will bestow upon you." And the Messenger of Allah ﷺ said: The right hand of Allah is full and spending (the riches) liberally during day and night will not diminish (the resources of Allah). Don't you see what (an enormous amount of resources) He has spent since He created the heaven and the earth, and what is in His right hand has not decreased? His Throne is upon the water. And in His other hand is death, and He elevates and degrades (whom He likes).  

عَنْ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ قَالَ لِي أَنْفِقْ أُنْفِقْ عَلَيْكَ وَقَالَ رَسُولُ اللَّهِ ﷺ يَمِينُ اللَّهِ مَلأَى لاَ يَغِيضُهَا سَحَّاءُ اللَّيْلَ وَالنَّهَارَ أَرَأَيْتُمْ مَا أَنْفَقَ مُذْ خَلَقَ السَّمَاءَ وَالأَرْضَ فَإِنَّهُ لَمْ يَغِضْ مَا فِي يَمِينِهِ قَالَ وَعَرْشُهُ عَلَى الْمَاءِ وَبِيَدِهِ الأُخْرَى الْقَبْضُ يَرْفَعُ وَيَخْفِضُ
