Umm Salama said:

"The Prophet (ﷺ) used to interrupt his Qur’anic recitation. He would say: “Praise be to Allah, the Lord of all the worlds [al-hamdu li-llahi Rabbi ’l-'alamin], then he would pause, then he would say: “The All-Merciful, the All-Compassionate [ar-Rahmani r-Rahim],” then he would pause and recite: “Master of the Day of Reckoning [Maliki yawm-id'deen].”

حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ‏:‏ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ الأُمَوِيُّ، عَنِ ابْنِ جُرَيْجٍ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ‏:‏ كَانَ النَّبِيُّ صلى الله عليه وسلم، يَقْطَعُ قِرَاءَتَهُ، يَقُولُ‏:‏ الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ ثُمَّ يَقِفُ، ثُمَّ يَقُولُ‏:‏ الرَّحْمَنِ الرَّحِيمِ ثُمَّ يَقِفُ، وَكَانَ يَقْرَأُ مَلِكِ يَوْمِ الدِّينِ‏.‏
