“When the son of Adam wakes up

Abu Sa’id Al-Khudri reported: The Messenger of Allah صلى الله عليه وسلم said, “When the son of Adam wakes up, all of his body parts bow to the tongue and say: Fear Allah concerning us, we are only part of you. If you are upright, then we are upright; but if you are crooked, then we are crooked.”

[Sunan At-Tirmidhi, Book of Asceticism, Number 2407, Hasan]

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَفَعَهُ قَالَ  إِذَا أَصْبَحَ ابْنُ آدَمَ فَإِنَّ الْأَعْضَاءَ كُلَّهَا تُكَفِّرُ اللِّسَانَ فَتَقُولُ اتَّقِ اللَّهَ فِينَا فَإِنَّمَا نَحْنُ بِكَ فَإِنْ اسْتَقَمْتَ اسْتَقَمْنَا وَإِنْ اعْوَجَجْتَ اعْوَجَجْنَا
