In the first verse (16o) here, the recurring sense of grief that gripped the noble Companions after what happened at the battle of Uhud is being removed through elegant counsel. Verses 161-164 declare that the station of Allah's messenger is free of failings, that he exhibits the highest standard of trustworthiness, and that the very presence of his on the face of the earth is a great blessing and a favour shown to the people of the world.
Verses 165-167 explain the reason why Muslims faced hardships at Uhud, while refuting the view of the hypocrites alongwith it in Ali 'Imran 3:168 ⧉.
Towards the end, in verses 169-171, it has been said that those who lay down their lives in the way of Allah achieve the ultimate success, real, permanent and full. Details follow.
