Surah Al-Baqarah — Ayah 280 (2:280)
وَإِن كَانَ ذُو عُسۡرَةٖ فَنَظِرَةٌ إِلَىٰ مَيۡسَرَةٖۚ وَأَن تَصَدَّقُواْ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ ٢٨٠
English translation (Saheeh International)
And if someone is in hardship, then [let there be] postponement until [a time of] ease. But if you give [from your right as] charity, then it is better for you, if you only knew.
Brief commentary
If the person from whom you demand your debt is in hard times and is unable to repay the debt, then refrain from asking until he is able to obtain money and then pay the debt. And to give charity to him by not demanding the debt or giving up a part of it is better for you, if you knew its worth in the sight of Allah.
