And to Lord Allah has the Best Names, so you appeal to Him with them, and you shun those who pervert His Names, they will be rewarded for whatever they are doing.
The Best Names of the Lord are the Names submitted by the Best Book Adhikr. It is told in verse 17: 110: "You call Allah or you call the Impartial, whatever you call, to him belongs the Best Names". It is told in verse 59: 24: "He is Lord Allah, the Creator, the Producer, the Fashioner. To Him belong the Best Names. Whatever is in the heavens and earth glorifies Him; and He is the Exalted in Might, the Wise".
The Fujjar are hiding and rejecting Adhikr. So they are unaware of the Best Names of the Lord. It is told in verse 4: 117 that anyone from Fujjar calls besides Lord, he is a pervert and is calling the Satan. It is told in verse 41: 40: "Indeed, those who distort Lord's verses are not hidden from Lord. So, is he who is cast into the Fire the best or he who comes secure on the Day of Resurrection? Do whatever you wish, indeed Lord is Seeing whatever you are doing".
Moulana (Our Master) is Lord’s name, so whoever ascribes that name to any of His creatures including Messenger Muhammad, is a pervert as explained in verses 2: 286 and 9: 51. It is told in verse 22: 78: "All are commanded to the Lord, He is your Master, what a Best Master and what a Best Helper!" To holdfast Lord means to holdfast Adhikr. So only with Adhikr one will be guided into the Straightpath as explained in verses 3: 101-102. See explanation 3: 78; 5: 62-63; 6: 115, and 7: 37.
