Hadith 8:1628
Abu Bakr narrated to us, he said: Marwan bin Mu'awiyah narrated to us, from Sulayman, he said: I heard Dharr asking Ibrahim about the *muhrim* (pilgrim in ihram) whom the rain reaches, how should he act? He said: He should raise his garment over his head, and he should not cover his head.
حدثنا أبو بكر قال حدثنا مروان بن معاوية عن سليمان قال سمعت ذرا يسأل إبراهيم عن المحرم يصيبه السماء كيف يصنع قال يرفع قناعه فوق رأسه ولا يغطي رأسه
