Two of the Prophet's Companions left his house on a dark night and were led by two lights like lamps illuminating the way before them
Authentic hadithعن أنس رضي الله عنه : أن رجلين من أصحاب النبي صلى الله عليه وسلم خرجا من عند النبي صلى الله عليه وسلم في ليلة مظلمة ومعهما مثلُ المصباحين بين أيديهما، فلما افترقا، صار مع كل واحد منهما واحد حتى أتى أهله.
Anas (may Allah be pleased with him) reported: Two men from the Companions of the Prophet (may Allah's peace and blessings be upon him) left his house on a dark night and were led by two lights like lamps, illuminating the way before them. When they parted, each of them was accompanied by one of these lights until he came to his family.
Explanation
This Hadīth tells about a manifest miracle that occurred to two of the Companions of the Prophet (may Allah's peace and blessings be upon him). Some versions of the Hadīth identify them as ‘Abbād ibn Bishr and Usayd ibn Hudayr (may Allah be pleased with both of them). These two noble Companions were with the Prophet (may Allah's peace and blessings be upon him) on a very dark night wherein a person would not easily find his way. Therefore, Allah honored them with a miracle; He caused a light similar to the light of a lamp to appear before them to illuminate their way. When the two Companions parted, each had his own light leading him to his home safe and secure.
