Surat At-Tawba (The Repentance) - التوبة

لَّيْسَ عَلَى ٱلضُّعَفَآءِ وَلَا عَلَى ٱلْمَرْضَىٰ وَلَا عَلَى ٱلَّذِينَ لَا يَجِدُونَ مَا يُنفِقُونَ حَرَجٌ إِذَا نَصَحُوا۟ لِلَّهِ وَرَسُولِهِۦ مَا عَلَى ٱلْمُحْسِنِينَ مِن سَبِيلٍ وَٱللَّهُ غَفُورٌ رَّحِيمٌ ﴿٩١﴾

It shall be no crime in the weak, nor in the sick, nor in those who do not find what they should spend (to stay behind), so long as they are sincere to Allah and His Apostle; there is no way (to blame) against the doers of good; and Allah is Forgiving, Merciful;
