(Furqan) 25 : 31
وَكَذَٰلِكَ جَعَلْنَا لِكُلِّ نَبِيٍّ عَدُوًّا مِنَ الْمُجْرِمِينَ ۗ وَكَفَىٰ بِرَبِّكَ هَادِيًا وَنَصِيرًا
And just like that We have made an enemy from Mujirims for each Prophet; and sufficient is your Lord as a Guide and a Helper.
The Mujirims mentioned in 52 places in the Book such as in verses 7: 40; 10: 17; 32: 12, 22, and 36: 59 are the Arabic Quran reading Fujjar. They are enemies of the Lord, all Prophets, and believers as told in verses 41: 26-29 and 63: 4.
Today, the Safeguard Adhikr is codified as the Splendid Book. So whoever holdfasts It, It will Safeguard him from all calamities, disasters, diseases, and Hellfire as explained in verse 5: 48. See explanation 2: 256; 6: 55 and 10: 17.
