Sayyiduna Rafi' bin Khadij (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said to Sayyiduna Bilal (may Allah be pleased with him): Let there be light for the morning prayer, until, because of the light, people can see where their arrows fall (that is, they can see things that far away). I say: There is another hadith from Sayyiduna Rafi' (may Allah be pleased with him) about praying in the light, other than this one.
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir.
