How can I tell if it's waswas or a real doubt about my prayer?
Alhamdulillah, I just prayed 'Asr at the masjid. I got there during the fourth rak'ah, so I prayed three by myself (of course). Now I've finished, and I'm not totally sure if I did three or four rak'at in total. I think it was four, but I can't say for certain. In our deen, certainty is really important, but we also can't let waswas take over. So how am I supposed to know which is which? By the way, I did the sajdah al-sahw just to be safe.
