فَلَمَّا ذَهَبَ عَنْ إِبْرَٰهِيمَ ٱلرَّوْعُ وَجَآءَتْهُ ٱلْبُشْرَىٰ يُجَٰدِلُنَا فِى قَوْمِ لُوطٍ
Commentary:
The fear of Abraham was not concerning his own person but concerning the people of Lot, an evidence of his great righteousness and nobility of character. The news first came to Abraham as a great shock. He did not know what to do. But when he was given the cheering news of the birth of a son who was to be the father of a great nation, he felt some relief and then began to plead with God for the doomed people.
See Gen. 18: 21-33.
