(Annajm) 53 : 37
وَإِبْرَاهِيمَ الَّذِي وَفَّىٰ

And Ibrahim who had fulfilled the promises.

The disbelieving addressees of Messenger Muhammed at Macach were the progenies of Messengers Ibrahim and Ismael. But these progenies have strayed from the Starightpath gradually. Even though they were leading a life against the dos and don’ts of the Book of Ibrahim, they were arguing and priding that they are following the lifeway of their forefathers Ibrahim and Ismael. Through this verse the literate believers are asked that are you leading a life according to the dos and don’ts of the Book of Ibrahim who lived fulfilling the covenant. See explanation 7: 172-173.
Today the Arabic Qur’an reading Fujjar whose ledger is in Sijjeen of the hell don’t follow Adhikr which is the Truth from the Lord. Instead they are following the falsehood books written by the pseudo prophets as explained in verse 2: 79, and are priding and boasting that they are the followers of Messenger Muhammed and are the inmates of the Paradise. Actually they are killing all Messengers and prophets by accepting their names without following their way of life as explained in verses 3: 21-22. These Fujjar are obliged to familiarise Allah as the Lord of mankind, the King of mankind, and the Single Deity of mankind to entire mankind. But without doing their duty, they are leading the mankind to the darkness from the Light so that they are denoted as the worst creatures among thousand communities of Lord through the verses 8: 22, and 55. See explanation 36: 6-11; 43: 22-23; and 87: 16-19.
