Arabic hadith text
وَحَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ لَقَدْ رَأَيْتُنِيأَفْتِلُ الْقَلاَئِدَ لِهَدْىِ رَسُولِ اللَّهِ صلى الله عليه وسلم مِنَ الْغَنَمِ فَيَبْعَثُ بِهِ ثُمَّ يُقِيمُ فِينَا حَلاَلاً .
Translation
'A'isha (Allah be pleased with her) reported
I recall how I wove garlands for the sacrificial animals (the goats) of Allah's Messenger (ﷺ). He sent them and then stayed with us as a non-Muhrim.
