يَحْلِفُوْنَ بِاللّٰهِ لَكُمْ لِيُرْضُوْكُمْ وَاللّٰهُ وَرَسُوْلُهٗٓ اَحَقُّ اَنْ يُّرْضُوْهُ اِنْ كَانُوْا مُؤْمِنِيْنَ ( التوبة: ٦٢ )
yahlifoona billaahi lakum liyurdookum wallaahu wa Rasooluhoo ahaqqu ai yurdoohu in kaanoo mu'mineen (at-Tawbah 9:62)
They swear by Allah to you [Muslims] to satisfy you. But Allah and His Messenger are more worthy for them to satisfy, if they were to be believers. (At-Tawbah  : 62)
1 Mufti Taqi Usmani
(O believers,) they swear by Allah before you, so that they may please you, whereas Allah, as well as His Messenger, has greater right that they should please Him, if they are (true) believers.
