Hadith 5:32
Abu Dharr (May Allah be pleased with him) reported:
I stepped out one night and saw the Messenger of Allah (ﷺ) walking by himself. I began to walk in the moonlit night. He turned round and saw me and asked, "Who is there?" I replied: "Abu Dharr." [Al-Bukhari and Muslim] .
وعن أبي ذر رضي الله عنه قال: خرجت ليلة من الليالي، فإذا رسول الله صلى الله عليه وسلم يمشي وحده، فجعلت أمشي في ظل القمر، فالتفت فرآني فقال: "من هذا؟" فقلت: أبو ذر، ((متفق عليه)).
