NAME: الإنسان، الدهر, Al-Insan, Ad-Dahr.

This Surah has two names and both taken from verse # 1.

١  هَلْ أَتَىٰ عَلَى الْإِنْسَانِ حِينٌ مِنَ الدَّهْرِ لَمْ يَكُنْ شَيْئًا مَذْكُورًا
1  Has there [not] come upon man a period of time when he was not a thing [even] mentioned?

But It does not mean that this name is the actual topic discussed in the whole Surah. It is just a reference and mark/symbol to distinguish this Surah from others as is with most other Surahs of Quran. While there are diversified topics discussed in these Surahs.

ENGLISH NAME: The Human/Man, Endless Time.
