Guidance and misguidance stand face to face in these verses: Allah guides whom He wills, His guidance is the true guidance, and the revealed Books carry it. The verses also speak of right conduct (rushd), recall that whoever is guided is guided for his own good, and distinguish the rightly guided believers from those deprived of Allah’s guidance, such as the wrongdoers and the disbelievers.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
And thus We have made you a median [i.e., just] community that you will be witnesses over the people and the Messenger will be a witness over you. And We did not make the qiblah which you used to face except that We might make evident who would follow the Messenger from who would turn back on his heels. And indeed, it is difficult except for those whom Allāh has guided. And never would Allāh have caused you to lose your faith [i.e., your previous prayers]. Indeed Allāh is, to the people, Kind and Merciful.
So whoever Allāh wants to guide - He expands his breast to [contain] Islām; and whoever He wants to send astray - He makes his breast tight and constricted as though he were climbing into the sky. Thus does Allāh place defilement upon those who do not believe.
