The master of Hadhrat Luqmaan Hakim once said to him, "Slaughter a goat and bring me the two best parts of its body." He slaughtered the goat and brought the heart and tongue to hi master.
The master then instructed him to slaughter a goat and bring the two worst parts of its body to him. He slaughtered a goat and brought the Heart and tongue to his master.
The master exclaimed, "How is it that you brought the same organs both times?" Hadhrat Luqmaan Hakim (peace be upon him) replied,
"My master, if the heart and tongue are pure, then there is no other part better than it in the entire body and if these two are spoilt, than there is no worst part than them. As long as they remain pure, they are the best and if they are evil then they are the worst."
