Sahih Muslim , Book 7, Hadith 2989 (USC-MSA) ⓘ

Yahya b. al-Husain reported on the authority of his grandfather that Allah's Apostle invoked blessing on the occasion of the Farewell Pilgrimage three times for those who got their heads shaved and once for those who got their hair clipped. In the narration transmitted by Waki' there is no mention of the Farewell Pilgrimage.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، وَأَبُو دَاوُدَ الطَّيَالِسِيُّ عَنْ شُعْبَةَ، عَنْ يَحْيَى بْنِ الْحُصَيْنِ، عَنْ جَدَّتِهِ، أَنَّهَا سَمِعَتِ النَّبِيَّ صلى الله عليه وسلم فِي حَجَّةِ الْوَدَاعِ دَعَا لِلْمُحَلِّقِينَ ثَلاَثًا وَلِلْمُقَصِّرِينَ مَرَّةً ‏.‏ وَلَمْ يَقُلْ وَكِيعٌ فِي حَجَّةِ الْوَدَاعِ ‏.‏
