It is reported from Sayyiduna Ali (may Allah be pleased with him) that when he said 'Sami'allahu liman hamidah', he would also recite: 'Allahumma rabbana lakal-hamd, Allahumma bi-hawlika wa quwwatika aqumu wa aq'ud' (O Allah, our Lord, all praise belongs to You. O Allah, by Your might and strength I stand and I sit).
