5/173. Chapter:
What was narrated concerning Qiyam (the voluntary night Prayers) during the month of Ramadan
Sunan Ibn Majah
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، عَنْ مُحَمَّدِ بْنِ عَمْرٍو، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ صَامَ رَمَضَانَ وَقَامَهُ إِيمَانًا وَاحْتِسَابًا، غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ " .
It was narrated that Abu Hurairah said: “The Messenger of Allah (ﷺ) said: ‘Whoever fasts Ramadan and spends its nights in prayer, out of faith and in hope of reward, his previous sins will be forgiven.’”
