God's Prophet (a.s) said: “Knowledge is useful if you use it rather than abide by your selfish (carnal) desires. Satan will run away from the shadow of anyone who overcomes his selfish desires. God the Almighty told the Prophet David (a.s): “It is forbidden to establish anyone who possesses knowledge but loves lustfulness as the leader of the pious people.”
قال رسول الله (صلى الله عليه وآله): من غلب علمه هواه فذاك علم نافع، ومن جعل شهوته تحت قدميه فر الشيطان من ظله، قال الله تعالى لداود (عليه السلام): حرام على كل قلب عالم محب للشهوات أن أجعله إماما للمتقين.
