(112) And thou hadst not expected that the Book would be sent to thee except as a mercy from thy Lord: Therefore lend not thou support in any way to those who reject (Allah's Message).

(113) "He punishes whom He pleases, and He grants mercy to whom He pleases, and towards Him are ye turned.

(114) Those who reject the Signs of Allah and the Meeting with Him (in the Hereafter),- it is they who shall despair of My mercy: it is they who will (suffer) a most grievous Penalty.

(115) And is it not enough for them that we have sent down to thee the Book which is rehearsed to them? Verily, in it is mercy and a Reminder to those who believe.

(116) And among His Signs is this, that He created for you mates from among yourselves, that ye may dwell in tranquillity with them, and He has put love and mercy between your (hearts): verily in that are Signs for those who reflect.

(117) When trouble touches men, they cry to their Lord, turning back to Him in repentance: but when He gives them a taste of mercy as from Himself, behold, some of them pay part-worship to other god's besides their Lord,-

(118) When We give men a taste of mercy, they exult thereat: and when some evil afflicts them because of what their (own) hands have sent forth, behold, they are in despair!

(119) Among His Signs is this, that He sends the Winds, as heralds of Glad Tidings, giving you a taste of His (Grace and) mercy,- that the ships may sail (majestically) by His Command and that ye may seek of His Bounty: in order that ye may be grateful.

(120) Then contemplate (O man!) the memorials of Allah's mercy!- how He gives life to the earth after its death: verily the same will give life to the men who are dead: for He has power over all things.
