This verse talks about the temporal absence of revelation for a while, which was for a great divine wisdom. The connection between the heavens and the earth is a through the Jibril (pbuh).
When the angel Jibril used to descend to the heart of the Prophet Muhammad (saws), his soul, body, movement, action and speech became in accordance to this revelation, that is why when the revelation paused, the Prophet (saws) was very sad, thus, the enemies of Islam and the Prophet (saws) took the chance to spread rumors that Muhammad’s Lord has abandoned him and hated him.
If the Holy Qur’an was written by a human, then he would say (nor has He detested you), but Allah (swt) does not mention the pronoun.
This is one of the great verses that shows Allah’s (swt) love and horour to His Prophet (saws); “goodbye forever” can be said to a beloved whereas, displeasing and unhappiness can be only towards enemies, that is why Allah (swt) does not mention (you) after the word (detested) and leaves it general.
