Sura al-Nisāʾ 4:65

فَلَا وَرَبِّكَ لَا يُؤْمِنُونَ حَتَّىٰ يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ ثُمَّ لَا يَجِدُوا۟ فِىٓ أَنفُسِهِمْ حَرَجًا مِّمَّا قَضَيْتَ وَيُسَلِّمُوا۟ تَسْلِيمًا

fa-lā warabbika lā yuʾminūna ḥattā yuḥakkimūka fī-mā shajara baynahum thumma lā yajidū fī anfusihim ḥarajan mimmā qaḍayta wa-yusallimū taslīman

But no, by the Lord, they can have no (real) Faith, until they make thee judge in all disputes between them, and find in their souls no resistance against Thy decisions, but accept them with the fullest conviction.

Sura al-Nisāʾ 4:103

فَإِذَا قَضَيْتُمُ ٱلصَّلَوٰةَ فَٱذْكُرُوا۟ ٱللَّـهَ قِيَٰمًا وَقُعُودًا وَعَلَىٰ جُنُوبِكُمْ فَإِذَا ٱطْمَأْنَنتُمْ فَأَقِيمُوا۟ ٱلصَّلَوٰةَ إِنَّ ٱلصَّلَوٰةَ كَانَتْ عَلَى ٱلْمُؤْمِنِينَ كِتَٰبًا مَّوْقُوتًا

fa-idhā qaḍaytumu l-ṣalāta fa-idhkurū allāha qiyāman wa-quʿūdan wa-ʿalā junūbikum fa-idhā aṭmanantum fa-aqīmū l-ṣalāta inna l-ṣalāta kānat ʿalā l-muʾminīna kitāban mawqūtan

When ye pass (Congregational) prayers, celebrate Allah's praises, standing, sitting down, or lying down on your sides; but when ye are free from danger, set up Regular Prayers: For such prayers are enjoined on believers at stated times.
