وعن أبي سعيد الخدري رضي الله عنه عن
النبي صلى الله عليه وسلم قال: «إذا أصبح ابن آدم، فإن الأعضاء كلها تكفر اللسان، تقول: اتقِ الله فينا، فإنما نحن بك: فإن استقمت استقمنا وإن اعوججت اعوججنا»
The Prophet (sallallahu alayhi wa sallam) said, “When the son of Adam gets up in the morning, all the limbs humble themselves before the tongue and say: ‘Fear Allah for our sake because we are with you: (i.e., we will be rewarded or punished as a result of what you do) if you are straight, we will be straight; and if you are crooked, we will become crooked.’”.
