Hadith 8:983
Abu Bakr narrated to us, he said: Waki’ and Abu Dawud al-Tayalisi narrated to us, from Shu’bah, from Yahya ibn al-Husayn, from his grandmother, that she heard the Prophet, may Allah bless him and grant him peace, during the Farewell Pilgrimage, pray for those who shave their heads three times, and for those who shorten their hair once. And Waki’ did not say "during the Farewell Pilgrimage."
حدثنا أبو بكر قال حدثنا وكيع وأبو داود الطيالسي عن شعبة عن يحيى بن الحصين عن جدته أنها سمعت النبي صلى الله عليه وسلم في حجة الوداع دعا للمحلقين ثلاثا وللمقصرين مرة ولم يقل وكيع في حجة الوداع
