Anyone whose heart God has opened up to Islam possesses a light from his Lord. But woe betide those whose hearts have been hardened against the rememberance of God! Such people are in obvious error. 22 Allah has revealed the best teaching, a self-consistent Book which repeats its contents in manifold forms whereat shiver the skins of those that hold their Lord in awe, and then their skins and their hearts soften for Allah's remembrance. That is Allah's Guidance wherewith He guides whosoever He pleases. And he whom Allah does not guide to the Right Path has none to guide him. 23 Is he then who has to guard himself with his own person against the evil chastisement on the resurrection day? And it will be said to the unjust: Taste what you earned. 24 Those before them had denied, then punishment had overtaken them is from a quarter they did not suspect. 25 So Allah made them taste disgrace in worldly life. But the punishment of the Hereafter is greater, if they only knew. 26 And assuredly We have propounded for mankind in this Qur'an all kinds of similitudes, that haply they may be admonished. 27 It is an Arabic Koran free from all crookedness, in order that they will be cautious. 28 Allah has struck an example of a man shared by disagreeing partners, and a man who is owned by just one man, are the two equally alike? Praise belongs to Allah, but most of them do not know. 29 Thou art mortal, and they are mortal; 30 Then verily on the Day of Resurrection, before your Lord ye shall contend. 31
