It is God who hath created you in weakness, then after weakness hath given you strength: then after strength, weakness and grey hairs: He createth what He will; and He is the Wise, the Powerful.
And on the day whereon the Hour shall arrive, the wicked will swear
That not above an hour have they waited: Even so did they utter lies on earth:
But they to whom knowledge and faith have been given will say, "Ye have waited, in accordance with the book of God, till the day of Resurrection: for this is the day of the Resurrection-but ye knew it not."
On that day their plea shall not avail the wicked, neither shall they again be bidden to seek acceptance with God.
And now have we set before men, in this Koran, every kind of parable: yet if thou bring them a single verse of it, the infidels will surely say, "Ye are only utterers of vain things."
It is thus that God hath sealed up the hearts of those who are devoid of knowledge.
But do thou, Muhammad, bear with patience, for true is the promise of God; and let not those who have no firm belief, unsettle thee.
