Fear of the future is religiously unlawful, a Muslim cannot think that way. God is the One Who creates every single second of our lives. All the precautions you take might come back to you as troubles. For instance, you might think about saving money but that might all end up going for cancer treatment or somehow otherwise be spent. You buy a house and God makes it collapse on top of you. One cannot put his trust in such things, but only in God. Anything other than that would be very wrong and would offend God. - Harun Yahya
