Sunan Ibn Majah, Hadith 812 ⓘ
It was narrated that ‘Aishah said: “The Messenger of Allah, Abu Bakr, ‘Umar and ‘Uthman used to start their recitation with “All praises and thanks are to Allah, the Lord of all that exists. (Al- hamdu Lillahi Rabbil-‘Alamin).’” [1:2]
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنْ بُدَيْلِ بْنِ مَيْسَرَةَ، عَنْ أَبِي الْجَوْزَاءِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَفْتَتِحُ الْقِرَاءَةَ بِـ {الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ }
