Verse Quran
4:71 O ye who believe! Take your precautions, and either go forth in parties or go forth all together.
4:102 When thou (O Messenger) art with them, and standest to lead them in prayer, Let one party of them stand up (in prayer) with thee, Taking their arms with them: When they finish their prostrations, let them Take their position in the rear. And let the other party come up which hath not yet prayed - and let them pray with thee, Taking all precaution, and bearing arms: the Unbelievers wish, if ye were negligent of your arms and your baggage, to assault you in a single rush. But there is no blame on you if ye put away your arms because of the inconvenience of rain or because ye are ill; but take (every) precaution for yourselves. For the Unbelievers Allah hath prepared a humiliating punishment.
9:50 If good befalls thee, it grieves them; but if a misfortune befalls thee, they say, "We took indeed our precautions beforehand," and they turn away rejoicing.
12:100 And he raised his parents high on the throne (of dignity), and they fell down in prostration, (all) before him. He said: "O my father! this is the fulfilment of my vision of old! Allah hath made it come true! He was indeed good to me when He took me out of prison and brought you (all here) out of the desert, (even) after Satan had sown enmity between me and my brothers. Verily my Lord understandeth best the mysteries of all that He planneth to do, for verily He is full of knowledge and wisdom.
