Hisnul Muslim
لَا إِلٰهَ إِلَّا اللّٰهُ وَحْدَهُ لَا شَرِيْكَ لَهُ، لَهُ الْمُلْكُ، وَلَهُ الْحَمْدُ، يُحْيِيْ وَيُمِيْتُ، وَهُوَ حَيٌّ لَا يَمُوْتُ، بِيَدِهِ الْخَيْرُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيْرٌ
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.
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.
At-Tirmithi 5/291, and Al-Hakim 1/538. Al-Albani graded it good in Sahih Ibn Majah 2/21 and Sahih At-Tirmithi 3/152.
