"So wait patiently for the command of your Lord"—for what He has ordained upon you therein and enjoined—"and do not obey any sinner among them," meaning the hypocrite; according to the interpretation of al-Hasan, one who manifests Islam while his heart is upon polytheism, "or an ungrateful disbeliever," meaning the polytheist who rejects the truth.
Interpretation of Surah al-Insan from verse (25-31)
﴿فاصبر لحكم رَبك﴾ لِمَا حَكَمَ عَلَيْكَ فِيهِ وَفَرَضَ ﴿وَلَا تُطِع مِنْهُم آثِما﴾ وَهُوَ الْمُنَافِقُ؛ فِي تَفْسِيرِ الْحَسَنِ أَظْهَرَ الإِسْلامَ وَقَلْبُهُ عَلَى الشِّرْكِ ﴿أَو كفورا﴾ وَهُوَ الْمُشرك الجاحد.
تَفْسِير سُورَة الْإِنْسَان من آيَة (٢٥ - ٣١)
