عَنْ أَبِي مُوسَى الْأَشْعَرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «تَعَاهَدُوا الْقُرْآنَ فَوَالَّذِي نَفْسِي بِيَدِهِ لَهْوَ أَشَدُّ تَفَصِّيًا مِنَ الْإِبِلِ فِي عُقُلِهَا»

Qatādā said that when Anas was asked how the Prophet recited the Qur’ān he replied that he did so prolonging the words. Then he recited “In the name of God, the Compassionate, the Merciful,” prolonging each phrase. Bukhārī transmitted it.
