"The stronger believer is better and more beloved to Allah than the weak believer, although both are good. Strive to seek that which will benefit you and do not feel helpless. If something overwhelms you, then say: Qaddarallah, wa ma sha'a fa'al (It is the decree of Allah and what He wills He does). And beware of (saying) "If only,' for "If only' opens the door to Satan."
