“Whoever enters a market place and says "Laa ilaaha illallaahu wahdahu laa shareeka lah, lahul mulku wa lahul hamdu yuhyee wa yumeetu wahuwa hayyun laa yamootu, biyadihi alkhayru wahuwa ala kulli shayyin qadeer - There is none worthy of worship in truth except Allah alone, He has no partners, He has the dominion and for him is all the praise, He gives life and he takes life and he is the ever living and does not die, in his hand is goodness and he is capable of all things." 

Allah will write for him thousand thousand reward and erase from him thousand thousand sin and raise him thousand thousand and build for him a house in Jannah!” - At-Tirmidhi
