They glorify His praises night and day, they never slacken.They persist in their worship night and day, obeying Allah to the utmost, and they are able to do this, as Allah says:لااَّ يَعْصُونَ اللَّهَ مَأ أَمَرَهُمْ وَيَفْعَلُونَ مَا يُوْمَرُونَwho do not disobey Allah in what He commands them, but do what they are commanded. (66:6)
