It is narrated from Hazrat Zaid bin Arqam (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) went to the people of Quba. They were performing prayer at the time of Duha. The Noble Prophet (peace and blessings be upon him) said: "The prayer of those who turn to Allah is performed at the time when the feet of the young camels begin to burn (from the heat of the sun)."
