Sajda-e-Sahw

Forgetting to make sajda-e-sahw

Q: I forgot to perform sajdah sahw which was wajib upon me during the first 4 rakats of sunnah namaz. Then I started Fardh namaz and once I finished fardh namaz I realised that I forgot to perform sajdah sahw for sunnat namaz. Is it permissible to perform the missed sajdah sahw of the sunnat namaz after the fardh prayer?

Sajda-e-sahw

Q: Dear Mufti Saheb, In Tuhaftul Almai, pg.219 vol.2, is mnentioned that when making sajdah sahw according to Imam Abu Haneefah, the correct method is to recite all the duas first, then make salaam to the right, then 2 sajdas and then recite tashahhud only, then salaam. Is this the correct procedure. If not, then what is the correct one? Would be grateful if you mention some hawalas.

Sajda-e-sahw

Q: Can you please explain uptil when sajda-e-sahw can be done for unintentionally missing out a wajib in the prayer? If a person unintentionally leaves out a wajib, and they have done salaam, can they still do sajda-e-sahw? Also, if a person does not do sajda-e-sahw, and the prayer time has ended, will they have to redo the prayer? I have heard that the prayer will have to be redone for leaving out a sajda-e-sahw as long as its still the prayer time, but after the prayer time has passed, it is not mandatory to redo the prayer, but recommended to. Please if you can explain.
