[BamSaitinypap]

According to the Hanbali madhab it is a obligatory action (at minimum to recite the supplication رب اغفر لي once) see page 1 and onwards of this PDF: http://www.ibnfarooq.com/Lessons/Lesson37[1].pdf but if it is left out forgetfully it can be compensaded by making sajdah sahw.

I had always wondered why the Hanafis don't say anything between the sujud, since according to them one should sit still motionless for the duration of saying once "SubhanAllah", by reciting once or as in the hadith twice "Rabbighirli" this duration is fulfilled. But they dont recite it and most of them don't even sit still motionless in between the sujud, rather they come up from the sujud and go down again in one movement. And such performed salaah is not valid according to the Malikis, Shafis, Hanbalis and according to Abu Yusuf.

i read the hanbali proof on this website ibnfarooq.com. and there is minimum to suggest from the Sunnat that its wajib. The author quoted this hadith:
The recitation of this supplication was the practice of ﷺ﴾ ﴿ ﷲ رسول till until he left this world. And He ﷺ﴾ ﴿ ordered
us in to pray as we have seen him pray. Narrated by al-Bukhārī.

i couldnt find this in saheeh bukhari. can anyone confirm if its there?and what supplication is mentioned here exactly?

just because hanbali ulema have agreed upon this doesnt make this wajib. and why have the saheeh hadith not have any referneces if they are sahih?take the first hadith on the first page for example. which book is it form?

i'll be glad if the guy himself can answer these.
