Does my prayer become invalid if I miss Subhaana rabbiyal-A’la?
In my school of thought, saying Subhaana rabbiyal-A’la is a must for the prayer to be valid. I know I have to say it, but sometimes, almost without me wanting to, my body just moves out of sujood too quickly, and I end up not saying it. Do I have to repeat the prayer, since I’m not really forgetting but also not doing it on purpose?
