[1] The good or bad quality that is found in a man springs from his natural temperament. If the temperament produces one quality, his other qualities will also be akin to this one because the dictates of temperament will be equally effective in either. Thus, if a man pays zakāt and khums it means that his temperament is not miserly. Therefore, it is expected that he would not be niggardly in spending in other items of charity as well. Similarly, if a man speaks a lie it can be expected that he will indulge in backbiting too, because these two habits are similar to each other.
