Hadith 11:160
Al-Muharibi narrated to us, from Abd al-Rahman ibn Ziyad ibn An'am, from Abdullah ibn Yazid, from Abdullah ibn Umar, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever suffers a headache in the way of Allah, Allah will forgive him for what has preceded of his sins."
حدثنا المحاربي عن عبد الرحمن بن زياد بن أنعم عن عبد الله بن يزيد عن عبد الله بن عمر قال قال رسول الله صلى الله عليه وسلم من صدع رأسه في سبيل الله غفر الله له ما تقدم من ذنبه
