Arabic (Original)
وَبِهَذَا الْإِسْنَادِ عَنْ فَضَالَةَ بْنِ عُبَيْدٍ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ كُلُّ مَيِّتٍ يُخْتَمُ عَلَى عَمَلِهِ إِلَّا الَّذِي مَاتَ مُرَابِطًا فِي سَبِيلِ اللَّهِ فَإِنَّهُ يَنْمُو عَمَلُهُ إِلَى يَوْمِ الْقِيَامَةِ وَيَأْمَنُ فِتْنَةَ الْقَبْرِ.
English Translation
And with this same chain, from Fadalah bin Ubayd, who said: I heard the Messenger of Allah, peace and blessings be upon him, say: Every deceased person has his deeds sealed, except the one who dies while guarding the frontier in the way of Allah, for his deeds continue to grow until the Day of Resurrection, and he is safe from the trial of the grave.
