The link between the two introductions is hidden in “kun” and it is the omitted waw for the meeting of the two sakīn. Likewise, if a man and a woman meet, there is no visible eye left for the pen, so his dropping the sperm into the womb is considered unseen because it is a secret, and that is why he expresses marriage secretly on the tongue. God Almighty said, “But no.” You date them secretly. Likewise, when reciting, they stop moving, and the pen can be hidden, just as the third letter, which is the waw, was hidden from the kanun, and the waw was because it has the height because it is generated from the nominative, and it is the satisfaction of the dhammah, and it is one of the vowels.
