Peace to all,
In Sufi terminology, there is a term, insan al-kamil which Ibn Arabi uses it to describe the Prophet Muhammad meaning the perfect human. It is based on hadith. I believe the term fits Abraham better. He represents the ideal human servant that I will never attain yet must strive to, nevertheless. He is the one chosen as God’s friend for a reason. He was a man of staunch faith in God thus he knew that nothing could cause him harm against the will of God. He gave us the first faith lesson with the fire incident that if we resign ourselves entirely to God, there is no need to fear or grieve, The same lesson is repeated in the sacrifice incident.
As 7:170 states, “We shall not deny the righteous their reward.” or 9:120, “God will not deny the righteous their reward”
So what was his reward? He was promised to be made an imam over mankind 2:124 The Jews, the Christians and even the idolatrous Arabs claimed him as their ancestor even though they did not practice his religion. That is his legacy. Peace to you Abraham!
