106:3 فَلْيَعْبُدُوا رَبَّ هَذَا الْبَيْتِ
Hence do not break your adoration and submission to one rearing, fostering and nourishing; as this will result in a state of being separated, disunited, scattered and unable to remain abode in adverse times. This is being made evident and clear to you.

وَآمَنَهُم مِّنْ خَوْفٍ
