 were it not for the coldness of the bladder the kidneys would burn the body and were it not for the heat of the kidneys the bladder would spoil a quarter of its body with its coldness. all of this is by the decree of the almighty the allknowing.
فلولا برد المثانة الكليتان الجسد ولولا حرارة الكليتين أفسدت المثانة ربعها ببردها. وكل ذلك بتقدير العزيز العليم.
