Appears 7 times in the Quran. (Root: سنو)
  1. And you will most certainly find them the greediest of men for life (greedier) than even those who are polytheists; every one of them loves that he should be granted a life of a thousand years, and his being granted a long life will in no way remove him further off from the chastisement, and Allah sees what they do.

  2. He said: So it shall surely be forbidden to them for forty years, they shall wander about in the land, therefore do not grieve for the nation of transgressors.

  3. And they ask you to hasten on the punishment, and Allah will by no means fail in His promise, and surely a day with your Lord is as a thousand years of what you number.

  4. And certainly We sent Nuh to his people, so he remained among them a thousand years save fifty years. And the deluge overtook them, while they were unjust.

  5. He regulates the affair from the heaven to the earth; then shall it ascend to Him in a day the measure of which is a thousand years of what you count.

  6. And We have enjoined on man doing of good to his parents; with trouble did his mother bear him and with trouble did she bring him forth; and the bearing of him and the weaning of him was thirty months; until when he attains his maturity and reaches forty years, he says: My Lord! grant me that I may give thanks for Thy favor which Thou hast bestowed on me and on my parents, and that I may do good which pleases Thee and do good to me in respect of my offspring; surely I turn to Thee, and surely I am of those who submit.

  7. To Him ascend the angels and the Spirit in a day the measure of which is fifty thousand years.
