It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Prophet of Allah (peace and blessings be upon him) entered the Quba' mosque while they were praying, when the sun had risen, and the Prophet of Allah (peace and blessings be upon him) said: "The oft-repentant (al-awwabin) used to offer this prayer when the feet of the young camels began to burn."
