“The Messenger of Allah ﷺ, 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] (Using translation from Ibn Mājah 812)
كَانَ رَسُولُ اللهِ ﷺ يَفْتَتِحُ الصَّلَاةَ بِالتَّكْبِيرِ وَيَفْتَتِحُ الْقِرَاءَةَ بِالْحَمْدُ لِلَّهِ
