Warn those who fear, through this (Qur'an), that they will be gathered before their Lord, and they will have none to protect or intercede for them apart from Him. They may haply take heed for themselves. 51 And do not drive away those who call upon their Lord in the morning and the evening, they desire only His favor; neither are you answerable for any reckoning of theirs, nor are they answerable for any reckoning of yours, so that you should drive them away and thus be of the unjust. 52 For it is in this way that We try men through one another - to the end that they might ask, "Has God, then, bestowed His favour upon those others in preference to us?" Does not God know best as to who is grateful [to Him]? 53 And when those who believe in Our signs come humbly in your presence, say to them, “Peace be upon you – your Lord has prescribed mercy for Himself by His grace – that whoever among you commits a sin by folly and thereafter repents and reforms (himself), then indeed Allah is Oft Forgiving, Most Merciful.” 54 Thus do We explain Our revelations so that the sinful way can be plainly discerned. 55
