It is narrated from Sayyiduna Qais bin Abi Ghazrah that in the blessed era of the Prophet (ﷺ), we traders were previously called brokers (samasirah). One day, the Prophet (ﷺ) came to us and said: O group of traders! The Prophet (ﷺ) addressed us with a better name than before. In trade, oaths and false statements also occur, so mix charity and alms into it.
