The Messenger of Allah ﷺ said, "Whoever enters a marketplace and says, 'There is no god but Allah, alone, with no partner. To Him belongs the dominion, and to Him belongs all praise. In His hand is all good. He gives life and causes death, and He has power over all things,' Allah will record for him a million good deeds, erase from him a million bad deeds, and build for him a house in Paradise."
حدثنا أبو سعيد حدثنا حماد بن زيد عن عمرو بن دينار مولى آل الزبير عن سالم عن أبيه
قال رسول الله ﷺ من قال في سوق لا إله إلا الله وحده لا شريك له له الملك وله الحمد بيده الخير يحيي ويميت وهو على كل شيء قدير كتب الله له بها ألف ألف حسنة ومحا عنه بها ألف ألف سيئة وبنى له بيتا في الجنة
Its isnad is extremely daif. Amr bin Dinar, Abu Yahya Basri, the one-eyed, steward of the household of Zubayr, about whom Ahmad said, daif, munkar al-hadith. Fallas and Nasai said, he narrated munkar hadiths from Salim. Ibn Hibban said, it is not permissible to record his hadith except out of astonishment, he used to narrate fabricated reports on his own authority from trustworthy narrators. He is different from Amr bin Dinar Makki Jumahi, the Imam.
