﴿فَإِذَا قَضَيْتُمُ الصَّلَاةَ فَاذْكُرُوا اللَّهَ قِيَامًا وَقُعُودًا وَعَلَىٰ جُنُوبِكُمْ ۚ فَإِذَا اطْمَأْنَنْتُمْ فَأَقِيمُوا الصَّلَاةَ ۚ إِنَّ الصَّلَاةَ كَانَتْ عَلَى الْمُؤْمِنِينَ كِتَابًا مَوْقُوتًا﴾
103. When you have finished As-Salât (the congregational prayer), remember Allâh standing, sitting down, and (lying down) on your sides, but when you are free from danger, perform As-Salât (Iqamat-as-Salât). Verily, As-Salât (the prayer) is enjoined on the believers at fixed hours.
