Al-Hadid (The Iron)

26. And verily, We sent Noah and Abraham and placed in their offspring Prophethood and Scripture. And among them there are some who are guided; but many of them are sinners.

The Prophets were appointed by God Almighty rather than by mankind. The preceding blessed Verse generally treated of sending the Prophets, but the blessed Verse in question deal with the Arch-Prophets, beginning with Noah and Abraham (as) and the Arch-Prophets, saying that God Almighty vested Prophethood and Scriptures with their offspring; nonetheless, all their offspring failed to benefit from such great heritage and Bounties. Some of them found Divine Guidance in their light, but many of them were faithless, corrupt, and disobedient to Allah.

Prophethood began with Noah (as) and it was passed down to Abraham (as) and other Arch-Prophets. Then, it was passed down to some of their offspring. However, a limited number benefited from the Light of Guidance, but the majority of mankind went astray.
