The Messenger of Allah ﷺ used to recite: "In the name of Allah, the Cherisher and Sustainer of the worlds; most Gracious, most Merciful; Master of the Day of Judgment," breaking its recitation into verses, one after another. Abu Dawud said: I heard Ahmad (b. Hanbal) say: The early reading is: Maliki yawmi'l-din. (Using translation from Abū Dāʾūd 4001)
عَنْ أُمِّ سَلَمَةَ ذَكَرَتْ أَوْ كَلِمَةً غَيْرَهَا قِرَاءَةَ رَسُولِ اللهِ ﷺ {بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ الرَّحْمَنِ الرَّحِيمِ مَالِكِ يَوْمِ الدِّينِ} يُقَطِّعُ قِرَاءَتَهُ آيَةً آيَةً
