The summary/theme of the surah Al-Anbiya:

 The Holy Prophet and the chiefs of Makkah were involved in the conflict at the time of its revelation, and this Surah deals with objections and doubts concerning his Prophethood, the Doctrines of Tauhid, and the Hereafter.

Lesson learned from surah Al-Anbiya:

1. The Day of Reckoning is drawing closer while we are still wandering in neglect.  
2. Ask the people who know if you yourself don’t know.  
3. Allah's cannot be questioned about what He does, whereas we will be questioned over our actions.  
4. Every soul shall taste death.  
5. The human is intrinsically hasty and impatient.
6. Allah's created every living thing from water.  
7. There will be thorough weighing of deeds on the Day of Judgement. 
8. Ayyūb عليه السلام was afflicted with a serious illness, but instead of asking Allah's to remove it, he merely mentioned it and said, ‘You are the most merciful from those who show mercy.’ He couldn’t bring himself to ask Allah's to remove it: such was his disposition.  
9. Allah's sent Muḥammad ﷺ as a mercy for the worlds.
