Do you say "  لَا إِلَٰهَ إِلَّا ٱللَّٰهُ مُحَمَّدٌ رَسُولُ ٱللَّٰهِ‎ " after completing salah , i have been doing this since my childhood , in my local mosque imam and everyone else says this , but in other local mosque they dont .

And do you wipe your face after completing salah ( i request you/ anyone to pls answer according to hanafi fiqh if you know, as i searched it on youtube but i got videos about wiping face after dua )

I have been doing the above things since childhood ( i was taught to pray salah this way ) but i stopped wiping my face after salah recently but i still do say لَا إِلَٰهَ إِلَّا ٱللَّٰهُ مُحَمَّدٌ رَسُولُ ٱللَّٰهِ‎  after finishing salah . I personally think these both are bidaah and i would completely stop them if they are .

Jazakallah u khairan
