الحمد لله الذي تلطف بعباده فتعبدهم بالنظافة، وأفاض على قلوبهم تزكية لسرائرهم أنواره وألطافه، وأعدّ لظواهرهم تطهيرا لها الماء المخصوص بالرقة واللطافة، … - Al-Ghazali

A fourth group of people climbs from ignorance and pretends to possess the rational faculty. They suppose that the highest felicity is the expansion of honor and fame, the spread of reputation, a multiplicity of followers, and the influence of the command that is obeyed. Hence, you see that their only concern is eye service and cultivation of the things upon which observers cast their glance. One of them may go hungry in his house and suffer harm so that he can spend his wealth on clothes with which to adorn himself so that no one will look at him with the eye of contempt when he goes out. The types of these people are beyond count. All of them are veiled from Allah by the sheer darkness that is their own dark souls.

A rational foe is better than an ignorant friend.

ثم تفكرت في نیتي في التدریس فإذا هي غیر خالصة لوجه الله تعالى ، بل باعثهاومحركها طلب الجاه وانتشار الصیت ؛ فتیقنت أني على شفا جُرُف هار ، وأني قدأشفیت على النار ، إن لم أشتغل بتلافي الأحوال.
