(631) And We made the son of Mary and his mother as a Sign: We gave them both shelter on high ground, affording rest and security and furnished with springs.

(632) If the Truth had been in accord with their desires, truly the heavens and the earth, and all beings therein would have been in confusion and corruption! Nay, We have sent them their admonition, but they turn away from their admonition.

(633) If We had mercy on them and removed the distress which is on them, they would obstinately persist in their transgression, wandering in distraction to and fro.

(634) Until We open on them a gate leading to a severe Punishment: then Lo! they will be plunged in despair therein!

(635) They will say, "To Allah!" say: "Yet will ye not receive admonition?"

(636) No son did Allah beget, nor is there any god along with Him: (if there were many gods), behold, each god would have taken away what he had created, and some would have lorded it over others! Glory to Allah! (He is free) from the (sort of) things they attribute to Him!

(637) "But ye treated them with ridicule, so much so that (ridicule of) them made you forget My Message while ye were laughing at them!

(638) He will say: "Ye stayed not but a little,- if ye had only known!

(639) "Did ye then think that We had created you in jest, and that ye would not be brought back to Us (for account)?"

(640) A sura which We have sent down and which We have ordained in it have We sent down Clear Signs, in order that ye may receive admonition.
