SHAFAQNA – When you engage in trade, first ask Allah (SWT) for all the good, trade at ease and do not make it difficult for each other in order to find blessing. Be kind to customers, have patience and do not swear or lie, do not be unjust, be fair to needy, do not approach usury, give proper weight and measure and do not steal from the scales and balances [1, 2].
