It was narrated that Nadr bin Shaiban said:“I met Abu Salamah bin ‘Abdur-Rahman and said: ‘Tell me a Hadith that you heard from your father, in which mention is made of the month of Ramadan.’ He said: ‘Yes, my father narrated to me that the Messenger of Allah (ﷺ) mentioned the month of Ramadan and said: “A month which Allah has enjoined upon you to fast, and in which I have established Qiyam (prayers at night) as Sunnah for you. So whoever fasts it and spends its nights in prayer out of faith and in hope of reward; he will emerge from his sins as on the day his mother bore him.”
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، وَعُبَيْدُ اللَّهِ بْنُ مُوسَى، عَنْ نَصْرِ بْنِ عَلِيٍّ الْجَهْضَمِيِّ، عَنِ النَّضْرِ بْنِ شَيْبَانَ، ح وَحَدَّثَنَا يَحْيَى بْنُ حَكِيمٍ، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، وَالْقَاسِمُ بْنُ الْفَضْلِ الْحُدَّانِيُّ، كِلاَهُمَا عَنِ النَّضْرِ بْنِ شَيْبَانَ، قَالَ لَقِيتُ أَبَا سَلَمَةَ بْنَ عَبْدِ الرَّحْمَنِ فَقُلْتُ حَدِّثْنِي بِحَدِيثٍ، سَمِعْتَهُ مِنْ، أَبِيكَ يَذْكُرُهُ فِي شَهْرِ رَمَضَانَ . قَالَ نَعَمْ . حَدَّثَنِي أَبِي أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ ذَكَرَ شَهْرَ رَمَضَانَ فَقَالَ " شَهْرٌ كَتَبَ اللَّهُ عَلَيْكُمْ صِيَامَهُ وَسَنَنْتُ لَكُمْ قِيَامَهُ فَمَنْ صَامَهُ وَقَامَهُ إِيمَانًا وَاحْتِسَابًا خَرَجَ مِنْ ذُنُوبِهِ كَيَوْمَ وَلَدَتْهُ أُمُّهُ " .
