Then you be patient; indeed the promise of Lord Allah is Truth, and let those who don’t have certainty weaken you.
The Arabic Quran reading Fujjar who hide and reject Adhikr are not having the certainty that the predictions of Adhikr will happen true. They are having never-ending doubt concerning every matter. In the Hereafter when they see the Hell they will wail as told in verse 32: 12: “We have seen the scene of the Hell and we have heard the sound of it, so You return us, we may do righteous deeds, indeed we have become the confirmed believers”.
The believer is commanded not to obey any among the Fujjar as explained in verse 25: 52. He is also commanded to do great Jihad against these Kuffar and hypocrites as explained in verse 9: 73. As he holdfasts the Safeguard Adhikr, he did holdfast Lord. So no harm will affect him anywhere in the universe as explained in verse 5: 48. See explanation 2: 5; 3: 79 and 17: 74-75.
