سنن ابن ماجه

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.”
