It was narrated from Ibn Abbas (RA) that: When the Prophet (صلی اللہ علیہ وسلم) wanted to prostrate after bowing, he would say: "Allahumma, Rabbana wa lakal-hamd, milas-samawati wa milal-ardi wa milama shita min shaiin bad ( O Allah, our Lord, to You be the Praise, filling the heavens, filling the Earth, and filling whatever else You will").
