And the disbelievers said, “Why was not a sign sent down upon him from his Lord?” Proclaim, “Indeed Allah sends astray whomever He wills, and guides towards Himself the one who comes towards Him.” 27 Those who believe and find peace in their hearts from the contemplation of God: Surely there is peace of heart in the contemplation of God!" 28 Those who believe and do right: Joy is for them, and bliss (their) journey's end. 29 Thus have We sent you (O Muhammad SAW) to a community before whom other communities have passed away, in order that you might recite unto them what We have inspired to you, while they disbelieve in the Most Beneficient (Allah) Say: "He is my Lord! La ilaha illa Huwa (none has the right to be worshipped but He)! In Him is my trust, and to Him will be my return with repentance." 30 If only a Koran whereby the mountains were set in motion, or the earth cleaved asunder, or the dead spoken to. No, but to Allah is the affair altogether. Do those who believe know that had Allah willed He could have guided all people? As for those who disbelieve, because of what they do, disaster will not cease to afflict them, or it alights near their home until the promise of Allah comes. Allah will not break His promise. 31
