لَّيْسَ عَلَى ٱلضُّعَفَآءِ وَلَا عَلَى ٱلْمَرْضَىٰ وَلَا عَلَى ٱلَّذِينَ لَا يَجِدُونَ مَا يُنفِقُونَ حَرَجٌ إِذَا نَصَحُوا۟ لِلَّهِ وَرَسُولِهِۦ ۚ مَا عَلَى ٱلْمُحْسِنِينَ مِن سَبِيلٍۢ ۚ وَٱللَّهُ غَفُورٌۭ رَّحِيمٌۭ
Not unto the weak nor unto the sick nor unto those who can find naught to spend is any fault (to be imputed though they stay at home) if they are true to Allah and His messenger. Not unto the good is there any road (of blame). Allah is Forgiving, Merciful.
Surah At-Tawba(9:91)
