"قال الشعبي: " لا أدري" نصف العلم. ومن سكت حيث لا يدري لله تعالي فليس بأقل أجراً ممن نطق لأن الاعتراف بالجهل أشد علي النفس ." - Al-Ghazali

كم ليال أحييتها بتكرار العلم، ومطالعة الكتب، وحرمت على نفسك النوم، ولا أعلم ما كان الباعث فيه! إن كان بنية عروض الدنيا وجذب حطامها وتحصيل مناصبها والمباهات على الأقران والأمثال فويل لك ثم ويل لك. وإن كان قصدك إحياء شريعة النبي صلى الله عليه وسلم، وتهذيب أخلاقك، وكسر النفس الأمارة بالسوء، فطوبى لك ثم طوبى لك.
ولقد صدق من قال
سهر العيون لغير وجهك باطل
وبكاؤهن لغير حسنك ضائع

if man’s love for himself be necessary, then his love for Him through whom, first his coming-to-be, and second, his continuance in his essential being with all his inward and outward traits, his substance and his accidents, occur must also be necessary. Whoever is so besotted by his fleshy appetites as to lack this love neglects his Lord and Creator. He possesses no authentic knowledge of Him; his gaze is limited to his cravings and to things of sense.

Praise be to God; whose compassion is all-embracing and Whose mercy is universal; Who rewards His servants for their remembrance [dhikr] [of Him] with His remembrance [of them] - verily God (Exalted is He!) has said, 'Remember Me, and I will remember you' - Opening lines from Kitab al-Adhkar wa'l Da'awat of the Ihya ulum ad-Din
