Surah Al-Furqan — Ayah 52 (25:52)
فَلَا تُطِعِ ٱلۡكَٰفِرِينَ وَجَٰهِدۡهُم بِهِۦ جِهَادٗا كَبِيرٗا ٥٢
English translation (Saheeh International)
So do not obey the disbelievers, and strive against them with it [i.e., the Qur’ān] a great striving.
Brief commentary
So do not follow the disbelievers in their demands for you to be soft with them and in the proposals that they put forward. Strive against them with this Qur’ān that is revealed to you a mighty struggle by being patient over their harm and tolerating difficulties in calling them to Allah.
