سنن ابن ماجه

It was narrated from Salim bin 'Abdullah bin 'Umar, from his father, that his grandfather told that the Messenger of Allah (ﷺ) said: "Whoever says, when he enters the marketplace: 'La ilaha illallah wahdahu la sharika lahu, lahul-mulk wa lahul-hamdu, yuhyi wa yumitu, wa Huwa hayyun la yamutu, bi yadihil-khairu kulluhu, wa Huwa ala kulli shay’in Qadir (None has the right to be worshiped but Allah alone, with no partner, to Him belongs all sovereignty and to Him is the praise, He gives life and gives death, and He is Ever-Living and does not die; in His Hand is all goodness and He is Able to do all things),' Allah will record for him one million good deeds, and will erase from him one million bad deeds, and will build for him a house in Paradise. "
