Sunan Ibn Majah, Volume 4, Book 25, Hadith 2935 (DarusSalam) ⓘ

It was narrated that ‘Aishah said: “We were with the Prophet, and we were in Ihram. When a rider met us we would lower our garments from the top of our heads, and when he has gone, we would lift them up again.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ، عَنْ مُجَاهِدٍ، عَنْ عَائِشَةَ، قَالَتْ كُنَّا مَعَ النَّبِيِّ ـ صلى الله عليه وسلم ـ وَنَحْنُ مُحْرِمُونَ فَإِذَا لَقِيَنَا الرَّاكِبُ أَسْدَلْنَا ثِيَابَنَا مِنْ فَوْقِ رُءُوسِنَا فَإِذَا جَاوَزَنَا رَفَعْنَاهَا ‏.‏
