Address

The triliteral root khā ṭā bā (خ ط ب) occurs in the Quran 12 times.

(11:37) "Construct the Ship under Our eyes and Our inspiration, and do not address to Me (Arab. تُخَاطِبْنِي, tukhāṭib'nī) regarding those who are wicked. They will be drowned."

Marriage proposal

(2:235) There is no blame upon you if you openly propose marriage (Arab. خِطْبَةِ, khiṭ'bati) to these women, or you keep it between yourselves. God knows that you will be thinking of them, but do not meet them secretly, unless you have something righteous to say. Do not consummate the marriage until the required interim is reached in the book. Know that God knows what is in your minds, so be conscientious of Him, and know that God is Forgiving, Compassionate.
