Prophet Abraham

His gelaran was khalilullah (kekasih Allah) and ketua kepada nabi dan rasul. He became the very first one to go against all the (1)idolatry and (2)worshiping of calestial bodies during his time(sun, stars, moon). And it all boiled down to him thinking. He was a real thinker. He was all alone initially. The only thing that makes him believe is Allah and Allah alone. No one else tells him anything. Not even a single other source of input.

The way how he did his dakwah was genius too. Being a thinker, he did not give his messages directly but he tried to make others think. He destroyed the idols. When ppl asked if it was him who did it, he said "ask the biggest idol". When he confronted the celestial bodies worshippers , he said "this is my lord" as he looked at the stars. And he then cancelled his claim because the stars in the end disappeared. And we know how the rest of the story goes. From this, we learn how one of the best ways to do dakwah is to make the people think themselves.

Aside from that, from prophet abraham's story, we see how Abraham as' father was adamant for Abraham to be a priest i.e follows his footsteps. And we see how the people in that era worshipped what they worshipped because thats what their forefathers did.
Andd...
If we check al baqarah (2):132-133, we see similar pattern. Similar but not the same. In 132 Abraham was adamant and strict as his father was. Allah siap guna perkataan wasiat. And in 133  the children and offstrings worship what the forefathers worship.

All this passing down of belief system and traditions that we see even in our lives are fitrah, but what the basis is, is all what's making the difference. We are one of the chains passing our belief system down to our offspring. We don't want to pass the wrong thing coz we now know "what forefathers do determine a lot on what the next generation will do".

We are the future forefathers.
