“In the science of the interpretation of dreams, wealth is represented by one’s liver. This is why giving alms is equivalent to giving away one’s life, as it were. When a person gives charity, they exhibit an immense degree of sincerity and steadfastness. However, the fact of the matter is that mere words are of no use until they are supported by practice. The reason charity is called ‘sadaqah’ in Arabic is because it is the hallmark of the Truthful (Sadiqin).”
