The Sahabah (may Allah be pleased with them) were the keenest of people to learn about their religion from the Prophet (blessings and peace of Allah be upon him) and to transmit what they learned to the Muslims who came after them. Prayer was foremost among the things that they wanted to learn and transmit, and it was their top priority. In this hadith, Anas ibn Malik (may Allah be pleased with him) tells us that the Prophet (blessings and peace of Allah be upon him), Abu Bakr (may Allah be pleased with him), and ‘Umar ibn al-Khattab (may Allah be pleased with him) after him, used to begin their prayer with {Al-hamdu Lillahi Rabbi l-‘Alamin} [al-Fatihah 1:2]. What is meant is that they did not recite the Basmalah (“Bismillah il-Rahman il-Rahim”) out loud. The first thing that could be heard of their recitation was the verse, {Al-hamdu Lillahi Rabbi l-‘Alamin}. This does not mean that they did not recite the opening supplication (du‘a’ al-istiftah) or words seeking refuge with Allah (isti‘adhah) at the beginning of the prayer, or recite the Basmalah quietly. Rather what is meant is that the first thing that they recited out loud after the takbir was {Al-hamdu Lillahi Rabbi l-‘Alamin}. This hadith indicates that one should not recite the Basmalah at the beginning of Surat al-Fatihah out loud. .
