(106) باب مَنْ أَشْعَرَ وَقَلَّدَ بِذِي الْحُلَيْفَةِ ثُمَّ أَحْرَمَ
Sahih al-Bukhari 1696 

Narrated `Aisha:

I twisted with my own hands the garlands for the Budn of the Prophet (ﷺ) who garlanded and marked them, and then made them proceed to Mecca; Yet no permissible thing was regarded as illegal for him then.

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا أَفْلَحُ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ فَتَلْتُ قَلاَئِدَ بُدْنِ النَّبِيِّ صلى الله عليه وسلم بِيَدَىَّ، ثُمَّ قَلَّدَهَا وَأَشْعَرَهَا وَأَهْدَاهَا، فَمَا حَرُمَ عَلَيْهِ شَىْءٌ كَانَ أُحِلَّ لَهُ‏.‏
