My problem is that while I was offering salah, I suddenly [by mistake] said something which may be shirk but I really didn`t believe in it. But I just can`t calm down!!!!!!!!!!!! I really love Allah and His prophets and I declare faith in the Oneness of Allah. However, many waswas come to me, I just ignore them, but I really don`t know what to do?????????????????? Have I done the unforgiveable sin??????????????? I can`t calm down!!!!!!!!!!!!!!!!!!
