By Allah, the Messenger of Allah ﷺ did not make Aisha perform umrah during Dhul-Hijjah but to discontinue the practice of the idolaters (in Arabia before Islam), for this clan of Quraysh and those who followed them used to say: When the fur of the camel abounds, and the wounds on the back of the camels are recovered and the month of Safar begins, umrah becomes lawful for one who performs umrah. They considered performing umrah unlawful till the months of Dhul-Hijjah and al-Muharram passed away.  

وَاللَّهِ مَا أَعْمَرَ رَسُولُ اللَّهِ ﷺ 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  

[Machine] And by Allah, the Messenger of Allah ﷺ did not perform Umrah with Aisha in Dhu al-Hijjah except to refute the statements of the polytheists. For this place is from Quraish, and whoever criticizes their religion, they used to say, "When the Yam (a type of fly) urinates and the donkey's tail is raised, then the Umrah is considered. So they used to prohibit Umrah until Dhu al-Hijjah and Muharram would pass. And by Allah, the Messenger of Allah ﷺ did not perform Umrah with Aisha except to fulfill their statement.  

وَاللهِ مَا اعْتَمَرَ رَسُولُ اللهِ ﷺ عَائِشَةَ فِي ذِي الْحِجَّةِ إِلَّا لِيَقْطَعَ بِذَلِكَ مِنْ قَوْلِ أَهْلِ الشِّرْكِ فَإِنَّ هَذَا الْحَيَّ مِنْ قُرَيْشٍ وَمَنْ دَانَ دِينَهُمْ كَانُوا يَقُولُونَ إِذَا عَفَا الْوَبَرْ وَبَرَأَ الدَّبَرْ وَدَخَلَ صَفَرْ فَقَدْ حَلَّتِ الْعُمْرَةُ لِمَنِ اعْتَمَرْ فَكَانُوا يُحْرِمُونَ الْعُمْرَةَ حَتَّى يَنْسَلِخَ ذُو الْحِجَّةِ وَالْمُحَرَّمُ فَوَاللهِ «مَا أَعْمَرَ رَسُولُ اللهِ ﷺ عَائِشَةَ إِلَّا لِيَقْضِيَ ذَلِكَ مِنْ قَوْلِهِمُ»  

By Allah, the Messenger of Allah ﷺ did not make Aisha perform umrah during Dhul-Hijjah but to discontinue the practice of the idolaters (in Arabia before Islam), for this clan of Quraysh and those who followed them used to say: When the fur of the camel abounds, and the wounds on the back of the camels are recovered and the month of Safar begins, umrah becomes lawful for one who performs umrah. They considered performing umrah unlawful till the months of Dhul-Hijjah and al-Muharram passed away. (Using translation from Abū Dāʾūd 1987)   

وَاللهِ مَا أعْمَرَ رَسُولُ اللهِ ﷺ عَائِشَةَ فِي ذِي الْحِجَّةِ إِلَّا لِيَقْطَعَ بِذَلِكَ أَمْرَ أَهَلِ الشِّرْكِ فَإِنَّ هَذَا الْحِيُّ مِنْ قُرَيْشٍ وَمَنْ دَانَ دِينَهُمْ كَانُوا يَقُولُونَ إِذَا عَفَا الْوَبَرْ وَبَرَأَ الدَّبَرْ وَدَخَلَ صَفَرْ حَلَّتِ الْعُمْرَةُ لِمَنِ اعْتَمَرْ وَكَانُوا يُحْرِمُونَ الْعُمْرَةَ حَتَّى يَنْسَلِخَ ذُو الْحِجَّةَ وَالْمُحَرَّمُ
