"I heard the Messenger of Allah (ﷺ) saying: 'Whoever goes to the Morning prayer first thing in the morning, he goes out with the banner of faith but whoever goes out to the marketplace first thing in the morning, he goes out under the banner of Iblis (Satan).' "
Sunan Ibn Majah Book 12, Hadith 98
← Previous Hadith the Messenger of Allah (ﷺ) went to the market of Nabit, and looked at it, and said: "This is not a market for you." Then we went to another market and looked at it, and said: "This is not a market for you." Then he came back to this market and walked around in it then he said: "This is your market. It will always be your market and no duty will be levied on it." (Do,if)

Sunan Ibn Majah Book 12, Hadith 97 Next Hadith → "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. "
