Surah Al-A'raf (The Heights), Verse 29

قُلْ اَمَرَ رَبِّیْ بِالْقِسْطِ وَاَقِیْمُوْا وُجُوْهَكُمْ عِنْدَ كُلِّ مَسْجِدٍ وَّادْعُوْهُ مُخْلِصِیْنَ لَهُ الدِّیْنَ كَمَا بَدَاَكُمْ تَعُوْدُوْنَ ۟

Qul amara Rabbee bilqisti wa aqeemoo wujoohakum 'inda kulli masjidin wad'oohu mukhliseena lahud deen; kamaa bada akum ta'oodoon

“Say: "My Lord hath commanded justice; and that ye set your whole selves (to Him) at every time and place of prayer, and call upon Him, making your devotion sincere as in His sight: such as He created you in the beginning, so shall ye return."”
