كَانَتِ

Appears 4 times in the Quran. (Root: كون)
  1. And surely I fear my cousins after me, and my wife is barren, therefore grant me from Thyself an heir,

  2. He said: O my Lord! when shall I have a son, and my wife is barren, and I myself have reached indeed the extreme degree of old age?

  3. O would that it had made an end (of me):

  4. On the day when the earth and the mountains shall quake and the mountains shall become (as) heaps of sand let loose.
