Sahih Muslim — Hadith 2699
Narrated by Abu Hurairah
مَنْ نَفَّسَ عَنْ مُؤْمِنٍ كُرْبَةً مِنْ كُرَبِ الدُّنْيَا نَفَّسَ اللَّهُ عَنْهُ كُرْبَةً مِنْ كُرَبِ يَوْمِ الْقِيَامَةِ وَمَنْ يَسَّرَ عَلَى مُعْسِرٍ يَسَّرَ اللَّهُ عَلَيْهِ فِي الدُّنْيَا وَالآخِرَةِ
Translation
The Prophet said: 'Whoever relieves a believer of a hardship of this world, Allah will relieve him of a hardship on the Day of Resurrection. Whoever makes things easy for one in difficulty, Allah will make things easy for him in this world and the Hereafter.'
Commentary
This hadith establishes a divine reciprocity: acts of compassion in this world are met with divine compassion in the next. It motivates social responsibility by connecting worldly kindness directly to eschatological reward, making charity and aid not just ethical duties but spiritually transformative acts.
