Sunan Ibn Majah, Volume 4, Book 25, Hadith 2925 (DarusSalam) ⓘ
It was narrated from Jabir bin ‘Abdullah that the Messenger of Allah said: “There is no Muhrim (pilgrim in Ihram) who exposes himself to the sun all day for the sake of Allah, reciting the Talbiyah until the sun goes down, but his sins will disappear and he will go back like on the day his mother bore him.”
حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ الْحِزَامِيُّ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نَافِعٍ، وَعَبْدُ اللَّهِ بْنُ وَهْبٍ، وَمُحَمَّدُ بْنُ فُلَيْحٍ، قَالُوا حَدَّثَنَا عَاصِمُ بْنُ عُمَرَ بْنِ حَفْصٍ، عَنْ عَاصِمِ بْنِ عُبَيْدِ اللَّهِ، عَنْ عَبْدِ اللَّهِ بْنِ عَامِرِ بْنِ رَبِيعَةَ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَا مِنْ مُحْرِمٍ يَضْحَى لِلَّهِ يَوْمَهُ يُلَبِّي حَتَّى تَغِيبَ الشَّمْسُ إِلاَّ غَابَتْ بِذُنُوبِهِ فَعَادَ كَمَا وَلَدَتْهُ أُمُّهُ " .
