That is because Allah is the Protector of those who believe, and those who disbelieve have no protector.
The Protector of believers is Allah, as Adhikr submits, whereas the protector of disbelievers is Satan, who obstructs mankind from Adhikr. The believer who holds Adhikr, the Unbreakable Rope mentioned in verse 2:256, is self-sufficient without depending on anyone other than Allah. Satan has no power except what Allah allows. Satan fulfils the wishes of disbelievers as told in verse 19:83 and beautifies their evil deeds as told in verses 6:42-43. There is Satan from Jinn and from mankind, as told in verses 6:112 and 114:6. As explained in verse 4:159, Satan will appear as Antichrist, whom Fujjar will accept first as prophet and later as Lord. At the second coming of Jesus, he will kill Antichrist, and people from Messenger’s community, such as Jains, Buddhists, Hindus, Jews, Christians, etc. will destroy these Fujjar. See explanation 8:48; 31:22; and 38:78, 82-83.
