حَدَّثَنَا هَنَّادُ بْنُ السَّرِيِّ، عَنِ ابْنِ أَبِي زَائِدَةَ، حَدَّثَنَا ابْنُ جُرَيْجٍ، وَمُحَمَّدُ بْنُ إِسْحَاقَ، عَنْ عَبْدِ اللَّهِ بْنِ طَاوُسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ وَاللَّهِمَا أَعْمَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَائِشَةَ فِي ذِي الْحِجَّةِ إِلاَّ لِيَقْطَعَ بِذَلِكَ أَمْرَ أَهْلِ الشِّرْكِ فَإِنَّ هَذَا الْحَىَّ مِنْ قُرَيْشٍ وَمَنْ دَانَ دِينَهُمْ كَانُوا يَقُولُونَ إِذَا عَفَا الْوَبَرْ وَبَرَأَ الدَّبَرْ وَدَخَلَ صَفَرْ فَقَدْ حَلَّتِ الْعُمْرَةُ لِمَنِ اعْتَمَرْ ‏.‏ فَكَانُوا يُحَرِّمُونَ الْعُمْرَةَ حَتَّى يَنْسَلِخَ ذُو الْحِجَّةِ وَالْمُحَرَّمُ

Narrated Abdullah ibn Abbas

By Allah, the Messenger of Allah (ﷺ) did not make Aisha perform 'umrah during Dhu'l-Hijjah except to put an end to the practice of the polytheists. For this tribe of Quraysh and those who followed their religion used to say: When the camel's fur grows thick, the camel's back heals from sores, and Safar begins, 'umrah becomes permissible for one who performs 'umrah. Thus, they used to consider 'umrah unlawful until Dhu'l-Hijjah and al-Muharram had passed.
