The Prophet ﷺ, Abu Bakr, and Umar, may Allah be pleased with them both, would start their recitation with: "All the praise and thanks be to Allah, the Lord of all that exists. (Using translation from Nasāʾī 902)
كَانَ النَّبِيُّ ﷺ وَأَبُو بَكْرٍ وَعُمَرُ يَسْتَفْتِحُونَ الْقِرَاءَةَ بِالْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ
