assalamu alaikum
I have some questions
1. when i start a new payer ex. fard prayer, then suunat prayer. i examine that my dress is ok or not. i never do it during prayer. do it just before start the salat. is it ok.
2. when i recite saliva comes to my mouth and i swollow it. sometimes it make sound but i never want to make sound. may be i have to ignore it. does it invalid salat.
3. i have read there are 36 wajib in salat. if i missed any one unintentionally. do i need sajda sawhi.
