At-Tawbah 9:86

Wa-itha onzilat sooratun an aminoobillahi wajahidoo maAAa rasoolihi ista/thanakaoloo attawli minhum waqaloo tharnanakun maAAa alqaAAideen

And when a sūrah was revealed [enjoining them] to believe in Allāh and to fight with His Messenger, those of wealth among them asked your permission [to stay back] and said, "Leave us to be with them who sit [at home]."

When a Sūrah is revealed (saying), “Believe in Allah and carry out Jihād in the company of His Messenger” the capable ones from them seek your permission and say, “Let us remain with those sitting back.”
