إذا مات الإنسان انقطع عنه عمله إلا من ثلاث: صدقة جارية، أو علم يُنتفع به، أو ولد صالح يدعو له
"When a person dies, their deeds come to an end except for three: an ongoing charity (sadaqah jariyah), knowledge from which others benefit, or a righteous child who prays for them."
— The Holy Prophet, peace be upon him and his family
