If a person completes his obligatory Salaat and reads some Du’aa afterward (Ta’qeebaat) but stands up from his prayer rug and wants to come back a few minutes later (maybe some important or time-sensitive issue occurs), then is it beneficial to resume Ta’qeebaat or, is the door of opportunity closed after completing Sajdah Shukr the first time?

If we see literal meaning of Taqibaat is has been derived from “Aqab” which means after of back therefore Taqibaat means what we recite “just after” finishing or completing our Namaz but if anyone due to something makes a gap between Namaz and Taqibat it’s okay. But what is better it has to be said just after the Namaz.
