Reciting in one's mind in Salaah
Q: A few years had passed where I used to recite Qirat and tasbeehaat in Salaah silently. Do I need to repeat all those Salaah? Most of my Salaah I performed was with jamaat. However, in that 8 year period I am not sure how many Salaah I performed individually. How would I calculate how many Salaah I need to redo in this instance?
