عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: مَنْ أَضْحَى يَوْمًا مُحْرِمًا مُلَبِّيًا حَتَّى غَرَبَتِ الشَّمْسُ غَرَبَتْ بِذُنُوبِهِ كَيَوْمِ وَلَدَتْهُ أُمُّهُ
Narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever spends a day in the state of Ihram, continuously reciting the Talbiyah until the sun sets, will be cleansed of his sins as if it were the day his mother gave birth to him.
