"So be patient; indeed, the promise of Allah is truth," which He promised you, that He will grant you victory over the polytheists. "And do not let those who are not certain unsettle you," meaning: do not follow the polytheists in what they invite you to of abandoning your religion.
﴿فَاصْبِرْ إِنَّ وَعْدَ اللَّهِ حَقٌّ﴾ الَّذِي وَعَدَكَ أَنَّهُ سَيَنْصُرُكَ عَلَى الْمُشْرِكِينَ. ﴿وَلا يَسْتَخِفَّنَّكَ الَّذِينَ لَا يوقنون﴾ أَيْ: لَا تُتَابِعِ الْمُشْرِكِينَ إِلَى مَا يَدْعُونَكَ إِلَيْهِ مِنْ تَرْكِ دِينِكَ.
