Bukhari

Hadith Commentary: In accordance with the verse, the hadith also mentions Prophet Yunus (alayhis salam); this is the reason for their correspondence.

Hadith Commentary:
➊
The reality is that Prophet Yunus (alayhis salam) exhibited impatience and surrendered himself to the sea, and remained for some time in the belly of the fish.
Upon witnessing this state of Prophet Yunus (alayhis salam), no person should claim, “I am better than him.” If anyone says such a thing, his statement is contrary to reality.
For indeed, he (Yunus alayhis salam) became even closer to Allah Ta’ala, and not even the slightest deficiency occurred in his rank.

➋
In the hadith, the word (أَنَا)
may refer to the Messenger of Allah (sallallahu alayhi wa sallam) himself, or it may refer to the speaker (i.e., the one making the claim).
If (أَنَا)
refers to the speaker, then the meaning is clear. And if it refers to the noble person of the Messenger of Allah (sallallahu alayhi wa sallam), then this is an expression of his humility and self-effacement, because the Messenger of Allah (sallallahu alayhi wa sallam) is superior to all the Prophets (alayhimus salam).

➌
In any case, the Messenger of Allah (sallallahu alayhi wa sallam), through this manner of expression, has safeguarded the sanctity of Prophet Yunus (alayhis salam) and removed people’s misconceptions about him. When the time comes to mention blessings, then one’s excellences will be stated; but for the time being, any disparagement of a Prophet is intolerable. In any case, the Messenger of Allah (sallallahu alayhi wa sallam) has warned the Ummah that, being influenced by the incident of the fish, no one should show disrespect towards the rank of a Prophet.
When the Messenger of Allah (sallallahu alayhi wa sallam) has stated this in such a manner, then how could it ever be permissible or appropriate for anyone else?
And Allah knows best.
