Surah Al-Baqarah, ayah 207

2:207

وَمِنَ ٱلنَّاسِ مَن يَشۡرِي نَفۡسَهُ ٱبۡتِغَآءَ مَرۡضَاتِ ٱللَّهِۚ وَٱللَّهُ رَءُوفُۢ بِٱلۡعِبَادِ ٢٠٧

Waminan-nāsi man yashrī nafsahubtighā'a mardātillāhi wallāhu ra'ūfu bil-'ibād

And of the people is he who sells himself, seeking means to the approval of Allāh. And Allāh is Kind to [His] servants.
