"Let those who dissent from His command beware," meaning the command of Allah, referring to the hypocrites, "lest a trial befall them," meaning a calamity, "or a painful punishment befall them," meaning that Allah brings out what is in their hearts of hypocrisy until they manifest it as shirk (polytheism); then He strikes them with killing because of that.
﴿فَلْيَحْذَرِ الَّذِينَ يُخَالِفُونَ عَنْ أَمْرِهِ﴾ عَنْ أَمْرِ اللَّهِ، يَعْنِي: الْمُنَافِقِينَ ﴿أَن تصيبهم فتْنَة﴾ بَلِيَّةٌ ﴿أَوْ يُصِيبَهُمْ عَذَابٌ أَلِيمٌ﴾ أَنْ يَسْتَخْرِجَ اللَّهُ مَا فِي قُلُوبهم من النافق حَتَّى يُظْهِرُوهُ شِرْكًا؛ فَيُصِيبَهُمْ بِذَلِكَ الْقَتْل
