 if you are impressed by your opinions then think about your mistakes and remember them and do not forget them. and in every opinion that you considered correct and it came out contrary to your estimation and someone else was right and you were wrong then if you do that then the least of your circumstances will be that the mistake of your opinion will balance out its correctness and you will come out with neither for you nor against you. and most likely your mistakes will be more than your correctness. and so it is with everyone after the prophets may gods prayers be upon them.
 وان أعجبت بآرائك، فتفكر في سقطاتك واحفظها ولا تنسها، وفي كل رأي قدرته صوابا فخرج بخلاف تقديرك، وأصاب غيرك وأخطأت انت، فانك ان فعلت ذلك فأقل أحوالك أن يوازن سقوط رأيك صوابه فتخرج لا لك ولا عليك، والأغلب أن خطأك أكثر من صوابك. وهكذا كل أحد من الناس بعد النبيين صلوات الله عليهم.
