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. (Using translation from Abū Dāʾūd 1635)
قَالَ رَسُولُ اللهِ ﷺ لَا تَحِلُّ الصَّدَقَةُ لِغَنِيٍّ إِلَّا لِخَمْسَةٍ لِغَازٍ فِي سَبِيلِ اللهِ أَوْ لِعَامِلٍ عَلَيْهَا أَوْ لِغَارِمٍ أَوْ لِرَجُلٍ اشْتَرَاهَا بِمَالِهِ أَوْ لِرَجُلٍ كَانَ لَهُ جَارٌ مِسْكِينٌ فَتَصَدَّقَ عَلَى الْمِسْكِينِ فَأَهْدَى الْمِسْكِينُ لِلْغَنِيِّ
