This narration has been declared a fabrication by the Muhaddithun. It is therefore not suitable to quote. Sayyiduna ‘Abdullah ibn ‘Umar (radiyallahu ‘anhuma) reported that Nabi (sallallahu ‘alayhi wa sallam) said: “Whoever remembers Allah in the marketplace once, Allah will remember him one hundred times.”(Refer: Tanzihush Shari’ah, vol. 2 pg. 322)

Although this narration is not suitable to quote, remembering Allah in the marketplace is indeed meritorious since people are usually negligent of Allah during trade.

Umar ibnul Khattab reported that the Rasulullah (sallallahu ‘alayhi wa sallam) said: ‘If a servant of Allah goes to the marketplace or shopping area and recites the following prayer then one million good deeds will be recorded for him and one million sins will be forgiven by Allah, who will also build a magnificent palace in Jannah for him.’

لا إِلٰه إلا اللُه وَحدَه لا شَريكَ لَه، له المُلْكُ وله الحَمْدُ، يُحْيِي وَيُمِيتُ، وَهو حَيٌّ لا يَمُوتُ بِيَدِه الخَيْرُ، وَهُوَ عَلٰى كُلّ شَيْءٍ قَدير
