The Saying When the Rooster Crows
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 68
وَقَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: «إِنَّ لِلَّهِ تَبَارَكَ وتَعَالَى مَلَكاً عَلَى صُورَةِ دِيكٍ أَبْيَضَ رَأْسُهُ تَحْتَ اَلْعَرْشِ وَ رِجْلاَهُ فِي تُخُومِ اَلْأَرْضِ اَلسَّابِعَةِ لَهُ جَنَاحٌ فِي اَلْمَشْرِقِ وَ جَنَاحٌ فِي اَلْمَغْرِبِ لاَ تَصِيحُ اَلدُّيُوكُ حَتَّى يَصِيحَ فَإِذَا صَاحَ خَفَقَ بِجَنَاحَيْهِ ثُمَّ قَالَ سُبْحَانَ اَللَّهِ سُبْحَانَ اَللَّهِ سُبْحَانَ اَللَّهِ اَلْعَظِيمِ اَلَّذِي «لَيْسَ كَمِثْلِهِ شَيْءٌ» قَالَ فَيُجِيبُهُ اَللَّهُ تَبَارَكَ وتَعَالَى وَ يَقُولُ لاَ يَحْلِفُ بِي كَاذِباً مَنْ يَعْرِفُ مَا تَقُولُ.
Imam Muhammad ibn Ali Al-Baqir عليه السلام said: "Indeed, Allah سبحانه وتعالى, Blessed and Exalted, has an angel in the form of a white rooster. Its head is beneath the Throne, and its feet are in the depths of the seventh earth. It has a wing in the east and a wing in the west. The earthly roosters do not crow until this angel crows. When it crows, it flaps its wings and says, 'Glory be to Allah سبحانه وتعالى, Glory be to Allah سبحانه وتعالى, Glory be to Allah سبحانه وتعالى, the Great, who is unlike anything.' Allah سبحانه وتعالى, Blessed and Exalted, responds and says, 'One who knows what you say will not swear falsely by Me.'".
