Sunan al-Tirmidhi #3428Hasan
لَا إِلَٰهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ، يُحْيِي وَيُمِيتُ، وَهُوَ حَيٌّ لَا يَمُوتُ، بِيَدِهِ الْخَيْرُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ
The Messenger of Allah (peace be upon him) said: 'Whoever enters the marketplace and says: La ilaha illallahu wahdahu la sharika lah, lahul-mulku wa lahul-hamdu, yuhyi wa yumit, wa Huwa Hayyun la yamut, biyadihil-khayr, wa Huwa 'ala kulli shay'in qadir — Allah will write for him a million good deeds, erase a million bad deeds, and raise him a million levels.'
