Saying to one's wife "I give you one"

Q: I am married and I had a argument with my wife. Whilst arguing one thing I said to her whilst in anger was “I will give you divorce” My intention
was that I would consider a talaaq not give a talaaq. We carried on arguing and I kept telling her to be quiet and speak to me slowly. She did not and this made me very angry and in that situation I said "I give you I give you one" realising that what I was about to say could break our marriage I stopped short of saying anything else. I did not mention the Talaaq  word when I said “I give you” as I realised what it would mean I had given divorce. It was not my intention to give talaaq, my intention was to stop the argument. I have been told that I have used kinayah words and because I had realised what it would mean if I had said the Talaq word and I stopped short of saying the actual word and I did not have intention of divorce, the Talaq has not taken place. Can you please confirm that what I have understood is correct. Please note I follow the Hanafi school of thought.

Not waking up for fajr Salaah

Q: It was narrated that Abu Sa’eed al-Khudri (may Allaah be pleased with him) said: A woman came to the Prophet (peace and blessings of Allaah be upon him) when we were with him and said: “O Messenger of Allaah, my husband Safwaan ibn al-Mu’attal does not pray Fajr until the sun has risen.” Safwaan was with him, so he asked him about what she had said, and he said: “O Messenger of Allaah, we are a family who are known not to wake up until the sun has risen.” He said: “When you wake up, then pray.” Narrated by Abu Dawood, 2459; classed as saheeh by Shaykh al-Albaani in Irwa’ al-Ghaleel, 7/65. 

I can't pray fajr salah because I have sleep problems.  I don't fall asleep easily and if I wake up for fajr I can't fall asleep again so can I pray fajr at zuhr time, would it be valid and am I a kafir if I don't pray fajr on time. Above hadith it says our prophet allowed a man to pray fajr after sunrise.
