QUESTION: We know it is sunnah to make ruku,standing after ruku,sijdah,sitting in between two sijdah almost equal in length.But if I want to make very big sijdah to make dua how can I make standing after ruku same in length.We know we can say Subhana rabbi al Atheem and rabbighfirli as many times as we want but is there anything like this in that position also?
