عَنْ أَبِي هُرَيْرَةَ رضى الله عنه
أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِذَا مَاتَ اَلْإِنْسَانُ اِنْقَطَعَ عَنْهُ عَمَلُهُ إِلَّا مِنْ ثَلَاثٍ: صَدَقَةٍ جَارِيَةٍ، أَوْ عِلْمٍ يُنْتَفَعُ بِهِ، أَوْ وَلَدٍ صَالَحٍ يَدْعُو لَهُ»
The Messenger of Allah (sallallahu alayhi wa sallam) said: “When a son of Adam (i.e. any human being) dies his deeds are discontinued, with three exceptions: Sadaqah, whose benefit is continuous; or knowledge from which benefit continues to be reaped, or a righteous child who supplicates for him.”.
