What was the reason for the revelation of Surah Al-Insan?

There are some accounts regarding the reasons for the revelation (Asbab al-Nuzul) of Surat al-Insan that are not without scrutiny. Among them is what was mentioned about an Abyssinian man asking the Prophet (peace be upon him) about their superiority over the Abyssinians and about the reward for faith. So, the verses from Surat al-Insan were revealed, clarifying the creation of man and his guidance. It was also mentioned that the reason for the revelation of the verse "And obey not among them a sinner or an ungrateful disbeliever" was due to Abu Jahl's threat to the Prophet (peace be upon him).
