ٱدْعُوا۟ رَبَّكُمْ تَضَرُّعًا وَخُفْيَةً ۚ إِنَّهُۥ لَا يُحِبُّ ٱلْمُعْتَدِينَ Qur’an Al-A'raf (7:55)OdAAoo rabbakum tadarruAAan wakhufyatan innahu la yuhibbu almuAAtadeena
In prayer, we must avoid any arrogance or show or loudness, or vanity of requests or words. If excess is condemned in all things, it is specially worthy of condemnation when we go humbly before Our Lord,-we poor creatures before the Omnipotent Who knoweth all.
