Call them as you may to the Right Path, they will not be ever guided aright. 57 Yet, [withal,] thy Sustainer is the Truly-Forgiving One, limitless in His grace. Were He to take them [at once] to task for whatever [wrong] they commit, He would indeed bring about their speedy punishment [then and there]: but nay, they have a time-limit beyond which they shall find no redemption 58 And these towns – We destroyed them when they committed injustice, and We had set an appointed time for their destruction. 59
