Abu Sa'id Al-Khudri (May Allah be pleased with him) said

The Prophet (ﷺ) 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."'
