In the holy Coran, many versets mention the notion of Barakah or blessing. This Barakah or blessing is a gift from God that gives to whom he wants from his servants. If the capital is blessed, it increases. If a child is blessed, he grows up a good child. If a human body is touched by this grace from God, it becomes healthy. If time is touched by God’s blessing, it is prolonged. If the Barakah touches the heart, it becomes happy. What is of interest to us for the moment is the financial blessing, the increase in revenue due to the presence of Barakah?
