Resolving of problems, ease of affairs, getting rid of afflictions caused by oneself or others, whether in this world or at the time of death, whether on the Day of judgment, the Day of Reckoning, or passing over (the bridge of) Sirat, are some of the results of piety. In this connection, the Lord of the universe says: “…and whoever is careful of (his duty to) Allah, He will make for him an outlet, and give him sustenance from whence he thinks not.”
As for those who will enter Hell, God says: “And there is not one of you but shall come to it; this is an unavoidable decree of your Lord. And We will deliver those who guarded (against evil) , and We will leave the unjust therein on their knees.” [1]
In another verse, God says: “And Allah shall deliver those who guard (against evil) with their achievement; evil shall not touch them, not shall they grieve.” [2]
Again in another verse, God has said: “…if you are patient and guard yourselves, their scheme will not injure you in any away.” [3]
It is obviously so, that all problems and entanglements related to this world and the hereafter arise from a kind of impiety and deviations whereas one, who guards against evil and exercises piety, is not only uninvolved in entanglements but lives in ease and with peace of mind.
