25:52
فَلَا تُطِعِ ٱلْكَـٰفِرِينَ وَجَـٰهِدْهُم بِهِۦ جِهَادًا كَبِيرًا
falā tuṭiʿi l-kāfirīna wajāhid'hum bihi jihādan kabīran
so do not give in to the disbelievers: strive hard against them with this Quran.
So obey not the disbelievers, but strive against them (by preaching) with the utmost endeavour with it (the Qur’ân).
