لَيْسَ عَلَى الضُّعَفَاۤءِ وَلَا عَلَى الْمَرْضٰى وَلَا عَلَى الَّذِيْنَ لَا يَجِدُوْنَ مَا يُنْفِقُوْنَ حَرَجٌ اِذَا نَصَحُوْا لِلّٰهِ وَرَسُوْلِهٖۗ مَا عَلَى الْمُحْسِنِيْنَ مِنْ سَبِيْلٍ ۗوَاللّٰهُ غَفُوْرٌ رَّحِيْمٌۙ ( التوبة: ٩١ )

Sahih International:
There is not upon the weak or upon the ill or upon those who do not find anything to spend any discomfort [i.e., guilt] when they are sincere to Allah and His Messenger. There is not upon the doers of good any cause [for blame]. And Allah is Forgiving and Merciful. (At-Tawbah [9] : 91)
1 Mufti Taqi Usmani
There is no blame on the weak, or on the sick, or on those who have nothing to spend, if they are sincere to Allah and His Messenger. There is no way against those who are good in deeds. Allah is most Forgiving, Very Merciful.
