It will be said to the Mujahid: Take from his noble deeds whatever you like. Then the Messenger of Allah (ﷺ) turned to us and asked: What do you think (will he leave anything)? - (i. e. he will take away everything).
وَحَدَّثَنَاهُ سَعِيدُ بْنُ مَنْصُورٍ، حَدَّثَنَا سُفْيَانُ، عَنْ قَعْنَبٍ، عَنْ عَلْقَمَةَ بْنِ مَرْثَدٍ، بِهَذَا الإِسْنَادِ ‏
"‏ فَقَالَ فَخُذْ مِنْ حَسَنَاتِهِ مَا شِئْتَ ‏"‏ ‏.‏ فَالْتَفَتَ إِلَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏"‏ فَمَا ظَنُّكُمْ ‏"‏ ‏.‏
