Hadith 8:981
Abu Bakr narrated to us, he said: Yazid narrated to us, he said: Muhammad ibn Ishaq informed us, from Ibn Abi Najih, from Mujahid, from Ibn Abbas, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "O Allah, forgive those who shave." He said it three times. They said: "O Messenger of Allah, what is the matter with those who shave that you have shown them mercy?" He said: "Because they did not doubt."
حدثنا أبو بكر قال حدثنا يزيد قال أخبرنا محمد بن إسحاق عن بن أبي نجيح عن مجاهد عن بن عباس قال قال رسول الله صلى الله عليه وسلم اللهم اغفر للمحلقين قال ثلاثا قال فقالوا يا رسول الله ما بال المحلقين ظاهرت لهم الترحم قال إنهم لم يشكوا
