Sayyiduna Fadalah bin Ubayd (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) heard a man supplicating in his prayer who neither glorified his Lord nor sent blessings upon his Prophet (peace and blessings be upon him), so the Prophet (peace and blessings be upon him) said: "This man has been hasty. When one of you prays, let him begin by glorifying his Lord and praising Him, then let him send blessings upon the Prophet (peace and blessings be upon him), then let him supplicate for whatever he wishes."
