It is narrated from Hazrat Anas (may Allah be pleased with him) that water was sprinkled on a corner of a mat for the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) offered two rak'ahs there. Upon hearing this, a man asked Hazrat Anas (may Allah be pleased with him), "Did the Prophet (peace and blessings be upon him) used to offer the Duha prayer?" He replied, "I only saw the Prophet (peace and blessings be upon him) offering that prayer on that day."
