Aspects of halaal and haram are extremely important. Someone asked Imaam Muhammad (rahmatullahi ‘alaih), the leading student of Imaam Abu Hanifah (rahmatullahi ‘alaih) that why is it that you have written so many kitaabs but no kitaab on tasawwuf. He replied that the purpose of tasawwuf is to cleanse oneself and have that connection with Allah Ta‘ala, and this is based on one’s consumption of halaal and haraam. Hence, I have written a book on business dealings since every person is engaged in some type of business which then gets him involved in halaal and haraam. Thus how important it is to get our business dealings in order.
Among the most important things for ensuring halaal is the aspect of contentment. With contentment, you will get barkat which will manifest at times in your very lifetime and sometimes after you leave this world. Therefore, lead a simple and basic life. One’s family members will complain that the whole world moves in good cars, goes on holidays, has this type of clothing for their children etc., and in order to appease them one puts himself into greater problems. Hence, instil the quality of contentment and there will be no problem.
