The Prophet ﷺ said: Sadaqah may not be given to rich man, with the exception of five classes: One who fights in Allah's path, or who collects it, or a debtor, or a man who buys it with his money, or a man who has a poor neighbour who has been given sadaqah and gives a present to the rich man.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ تَحِلُّ الصَّدَقَةُ لِغَنِيٍّ إِلاَّ لِخَمْسَةٍ لِغَازٍ فِي سَبِيلِ اللَّهِ أَوْ لِعَامِلٍ عَلَيْهَا أَوْ لِغَارِمٍ أَوْ لِرَجُلٍ اشْتَرَاهَا بِمَالِهِ أَوْ لِرَجُلٍ كَانَ لَهُ جَارٌ مِسْكِينٌ فَتُصُدِّقَ عَلَى الْمِسْكِينِ فَأَهْدَاهَا الْمِسْكِينُ لِلْغَنِيِّ
