Sa'id bin Nafi' said: Sayyiduna Abu al-Yusr (may Allah be pleased with him) saw me praying the Duha prayer. He forbade me and said: The Prophet (peace and blessings be upon him) said: "Do not pray until the sun has risen high, for it rises between the two horns of Shaytan."
Al-Bazzar recorded it, and its narrators are thiqat (trustworthy).
