Hadith.3726 - Imam Ali ibn Abi Talib (as) used to go out every morning in Kufa and walk through its markets, visiting them one by one. Imam (as) carried a whip with two ends, which was called "Al-Sabeebah." Imam (as) would stand in each market and call out to the merchants, saying: "O group of traders! Begin with seeking goodness (from Allah (swt)), bless your trade with ease, draw near to the buyers, adorn yourselves with patience, avoid oppression, give justice to the oppressed, and do not approach usury. 'And give full measure and weight' and 'Do not diminish people's goods, nor act corruptly in the land, making mischief.'" Then Imam (as) would continue walking through all the markets of Kufa before returning to sit and attend to the people's needs.
