حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ: قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ مَنْ صَامَ رَمَضَانَ إِيمَانًا وَاحْتِسَابًا غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ ‏"‏ ‏.‏
Translation
It wasnarrated from Abu Hurairah that the Messenger of Allah (ﷺ)said

“When the first night of Ramadan comes, the satans andmischievousjinns are chained up, and the gates of the Fire areclosed, and noneof its gates are opened. The gates of Paradise areopened and none ofits gates are closed. And a caller cries out: ‘Oseeker of good,proceed, O seeker of evil, stop.’ And Allah has necks(people) whomHe frees (from the Fire), and that happens every day.”
