Sunan Abi Dawud 1481
سنن أبي داود#1481SahihNarrated Fudalah ibn Ubayd,: The Messenger of Allah (ﷺ) heard a person supplicating during prayer. He did not mention the greatness of Allah, nor did he invoke blessings on the Prophet (ﷺ). The Messenger of Allah (ﷺ) said: He made haste. He then called him and said either to him or to any other person: If any of you prays, he should mention the exaltation of his Lord in the beginning and praise Him; he should then invoke blessings on the Prophet (ﷺ); thereafter he should supplicate Allah for anything he wishes
