Hadith 6:61
Ibn Abbas (RAA) narrated that the Messenger of Allah (ﷺ) said:
"Women (pilgrims) do not have to shave (their heads); they may only shorten their hair." Related by Abu Dawud with a good chain of narrators.
وَعَنِ اِبْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا, عَنِ اَلنَّبِيِّ - صلى الله عليه وسلم -قَالَ: { لَيْسَ عَلَى اَلنِّسَاءِ حَلْقٌ, وَإِنَّمَا يُقَصِّرْنَ } رَوَاهُ أَبُو دَاوُدَ بِإِسْنَادٍ حَسَنٍ
