(Tone of the Contact Prayers (Salat))
Say, “Call Him God, or call Him Most Gracious; whichever name you use, to Him belongs the best names.” You shall not utter your Contact Prayers (Salat) too loudly, nor secretly; use a moderate tone.
قُلِ ادعُوا اللَّهَ أَوِ ادعُوا الرَّحمٰنَ أَيًّا ما تَدعوا فَلَهُ الأَسماءُ الحُسنىٰ وَلا تَجهَر بِصَلاتِكَ وَلا تُخافِت بِها وَابتَغِ بَينَ ذٰلِكَ سَبيلًا
qulid’ul laaha awid’ur Rahmaana ayyam maa tad’oo falahul asmaaa’ul Husnaa; wa laa tajhar bi Salaatika wa laa tukhaafit bihaa wabtaghi baina zaalika sabeela
