Harithah reports that once some people from Syria came to Sayyiduna Umar Farooq (may Allah be pleased with him) and said, "We have acquired some wealth, horses, and slaves. We desire that there be means of purification and self-purification for us in this." Sayyiduna Umar Farooq (may Allah be pleased with him) said, "I will do as my two predecessors did before me." Then he consulted with the noble companions (may Allah be pleased with them), among whom Sayyiduna Ali (may Allah be pleased with him) was also present. He said, "This wealth is lawful, but on the condition that it is not made into a tax, so that it continues to be collected from people in the future."
