عَنْ عُمَرَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَنْ قَالَ فِي سُوقٍ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ بِيَدِهِ الْخَيْرُ يُحْيِي وَيُمِيتُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ كَتَبَ اللَّهُ لَهُ بِهَا أَلْفَ أَلْفِ حَسَنَةٍ وَمَحَا عَنْهُ بِهَا أَلْفَ أَلْفِ سَيِّئَةٍ وَبَنَى لَهُ بَيْتًا فِي الْجَنَّةِ
It is narrated from Sayyiduna Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever recites this supplication upon entering the marketplace: LAA ILAAHA ILLALLAHU WAHDAHU LAA SHAREEKA LAHU, LAHUL-MULKU WA LAHUL-HAMDU, BIYADIHIL-KHAIRU, YUHYEE WA YUMEETU, WA HUWA ‘ALAA KULLI SHAY’IN QADEER (There is no true deity except Allah, He is alone, He has no partner, sovereignty belongs to Him, all praise is for Him, in His hand is all good, He gives life and causes death, and He is powerful over everything), Allah Almighty will write for him one million good deeds, forgive one million of his sins, and build for him a house in Paradise.
