Hisn al-Muslim (Fortress of the Muslim) 51
((اللَّهُمَّ اكْتُبْ لِي بِهَا عِنْدَكَ أَجْراً، وَضَعْ عَنِّي بِهَا وِزْراً، وَاجْعَلْهَا لِي عِنْدَكَ ذُخْراً، وَتَقَبَّلْهَا مِنِّي كَمَا تَقَبَّلْتَهَا مِنْ عَبْدِكَ دَاوُدَ)).
(O Allah, record for me a reward for this (prostration), and remove from me a sin. Save it for me and accept it from me just as You had accepted it from Your servant Dawood.)
