...though it is hard for you. But it may be that a thing is hard upon you though it is (really) good for you, and it may be that you love a thing while it is bad for you. Allâh knows (all things) while you do not know. (Al Baqarah,2 : 216)
Say, `Did you ever consider if Allah's punishment were to overtake you unaware or (after) manifest (warnings), would any be destroyed except the wrongdoing people?' (Al An a'm,6 :47)
Every living being is destined to taste death. And you shall, verily, be paid in full your rewards on the Day of Resurrection. Then whoso is removed away from the Fire and is admitted to Paradise, he has, of course, successfully attained his goal. And the life of this world is nothing but a vain provision (causing negligence). (Ali Imran,3 :185)
You shall, certainly, be tried in your substance and lives and you shall certainly hear from those who were given the Scripture before you and from those who set up equals (to God) a good deal of hurtful abuse. But if you are patiently persevering and guard against evil, then this (attitude) is worth being followed with constancy and firm determination. (Ali Imran,3: 186)
It is He Who has created seven heavens, one upon another in conformity (with each other). You can see no flaw, no incongruity and no imperfection in the creation of the Most Gracious (God). Then look up once more (to heaven). Do you see any flaw? (Al Mulk ,67 :3)
