The Messenger of Allah ﷺ led us in the dawn prayer at Hudaybiyah following a rainfall that had occurred during the night. When he finished, he turned to face the people and said, and then he mentioned the rest of the hadith.
صلى لنا رسول الله ﷺ صلاة الصبح بالحديبية على أثر سماء كانت من الليلة، فلما انصرف أقبل على الناس فقال: فذكر بقية الحديث.
