ذِكْرُ الْبَيَانِ بِأَنَّ الْمُرَابِطَ الَّذِي يَجْرِي لَهُ أَجْرُ عَمَلِهِ بَعْدَ مَوْتِهِ إِنَّمَا هُوَ أَجْرُ عَمَلِهِ الَّذِي كَانَ يَعْمَلُ فِي حَيَاتِهِ مِنَ الطَّاعَاتِ
I heard the Messenger of Allah ﷺ say: Keeping watch for a day and a night is better (in point of reward) than fasting for a whole month and standing in prayer every night. If a person dies (while, performing this duty), his (meritorious) activity will continue and he will go on receiving his reward for it perpetually and will be saved from the torture of the grave. (Using translation from Muslim 1913a)
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «مَنْ مَاتَ مُرَابِطًا أُجْرِيَ عَلَيْهِ عَمَلُهُ الَّذِي كَانَ يَعْمَلُ وَأُومِنَ الْفَتَّانَ وَيَجْرِي عَلَيْهِ رِزْقُهُ»
