قُلِ ٱدْعُوا۟ ٱللَّهَ أَوِ ٱدْعُوا۟ ٱلرَّحْمَـٰنَ ۖ أَيًّا مَّا تَدْعُوا۟ فَلَهُ ٱلْأَسْمَآءُ ٱلْحُسْنَىٰ ۚ وَلَا تَجْهَرْ بِصَلَاتِكَ وَلَا تُخَافِتْ بِهَا وَٱبْتَغِ بَيْنَ ذَٰلِكَ سَبِيلًا

Say, "Call upon Allāh or call upon the Most Merciful [ar-Raḥmān]. Whichever [name] you call - to Him belong the best names." And do not recite [too] loudly in your prayer or [too] quietly but seek between that an [intermediate] way.
— Saheeh International
Say [to them], ‘Call on God, or on the Lord of Mercy- whatever names you call Him, the best names belong to Him.’ [Prophet], do not be too loud in your prayer, or too quiet, but seek a middle way
— M. A. S. Abdel Haleem
Say (O Muhammad صلى الله عليه و سلم): "Invoke Allâh or invoke the Most Gracious (Allâh), by whatever name you invoke Him (it is the same), for to Him belong the Best Names. And offer your Salât (prayer) neither aloud nor in a low voice, but follow a way between.
— Muhammad Muhsin Khan & Muhammad Taqi-ud-Din al-Hilali
