9 : 91
لَّيۡسَ عَلَى ٱلضُّعَفَآءِ وَلَا عَلَى ٱلۡمَرۡضَىٰ وَلَا عَلَى ٱلَّذِينَ لَا يَجِدُونَ مَا يُنفِقُونَ حَرَجٌ إِذَا نَصَحُواْ لِلَّهِ وَرَسُولِهِۦۚ مَا عَلَى ٱلۡمُحۡسِنِينَ مِن سَبِيلٖۚ وَٱللَّهُ غَفُورٞ رَّحِيمٞ
There is no blame on the weak, the sick, or those who have nothing to spend, as long as they are sincere to Allah and His Messenger. There is no blame on those who do good, and Allah is All-Forgiving, Most Merciful.
