لا إلهَ إلاّ اللّه وحدَهُ لا شريكَ لهُ، لهُ المُلْـكُ ولهُ الحَمْـد، يُحْيـي وَيُميـتُ وَهُوَ حَيٌّ لا يَمـوت، بِيَـدِهِ الْخَـيْرُ وَهوَ على كلّ شيءٍ قدير
Laa ilaaha illallaahu wahdahu laa shareeka lahu, lahul-mulku wa lahul-hamdu, yuhyee wa yumeetu, wa Huwa hayyun laa yamootu, biyadihil-khayru, wa Huwa alaa kulli shay in Qadeer.
None has the right to be worshipped but Allah alone, Who has no partner. His is the dominion and His is the praise. He brings life and He causes death, and He is living and does not die. In His Hand is all good, and He is Able to do all things.
