Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعنه قال: قال رسول الله صلى الله عليه وسلم : "إذا مات ابن آدم انقطع عمله إلا من ثلاث: صدقة جارية ،أو علم ينتفع به، أو ولد صالح يدعو له" ((رواه مسلم)).
The Messenger of Allah (ﷺ) said, "When a man dies, his deeds come to an end except for three things: Sadaqah Jariyah (ceaseless charity); a knowledge which is beneficial, or a virtuous descendant who prays for him (for the deceased)."[Muslim].
