Qur'ān 6:42 · Al-An'am (الأنعام)

وَلَقَدْ أَرْسَلْنَآ إِلَىٰٓ أُمَمٍۢ مِّن قَبْلِكَ فَأَخَذْنَـٰهُم بِٱلْبَأْسَآءِ وَٱلضَّرَّآءِ لَعَلَّهُمْ يَتَضَرَّعُونَ

And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us].
