Surah Al-Maeda Verse 108 - English Translation by A. J. Arberry
Surah Al-Maedaذَٰلِكَ أَدۡنَىٰٓ أَن يَأۡتُواْ بِٱلشَّهَٰدَةِ عَلَىٰ وَجۡهِهَآ أَوۡ يَخَافُوٓاْ أَن تُرَدَّ أَيۡمَٰنُۢ بَعۡدَ أَيۡمَٰنِهِمۡۗ وَٱتَّقُواْ ٱللَّهَ وَٱسۡمَعُواْۗ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلۡفَٰسِقِينَ
So it is likelier that they will bear testimony in proper form, or else they will be afraid that after their oaths, oaths may be rebutted. Fear God, and hearken; God guides not the people of the ungodly
