Narrated Umm Salamah, Ummul Mu'minin: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.
حَدَّثَنَا سَعِيدُ بْنُ يَحْيَى الأُمَوِيُّ، حَدَّثَنِي أَبِي، حَدَّثَنَا ابْنُ جُرَيْجٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي مُلَيْكَةَ، عَنْ أُمِّ سَلَمَةَ، أَنَّهَا ذَكَرَتْ - أَوْ كَلِمَةً غَيْرَهَا - قِرَاءَةَ رَسُولِ اللَّهِ صلى الله عليه وسلم{ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ * الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ * الرَّحْمَنِ الرَّحِيمِ * مَلِكِ يَوْمِ الدِّينِ }يَقْطَعُ قِرَاءَتَهُ آيَةً آيَةً . قَالَ أَبُو دَاوُدَ سَمِعْتُ أَحْمَدَ يَقُولُ الْقِرَاءَةُ الْقَدِيمَةُ { مَالِكِ يَوْمِ الدِّينِ } .
