فَاِذَا قَضَيْتُمُ الصَّلٰوةَ فَاذْكُرُوا اللّٰهَ قِيٰمًا وَّقُعُوْدًا وَّعَلٰي جُنُوْبِكُمْۚ فَاِذَا اطْمَاْنَنْتُمْ فَاَقِيْمُوا الصَّلٰوةَۚ اِنَّ الصَّلٰوةَ كَانَتْ عَلَي الْمُو͏ٔ͏ْمِنِيْنَ كِتٰبًا مَّوْقُوْتًا ١٠٣
Translation
When you have finished the prayers, remember Allah, standing, sitting, and lying down, and when you feel secure, perform the [complete] prayers, for the prayer is indeed a timed prescription for the faithful.
