The son of Sayyidina Abdullah ibn Mughaffal (RA) said that when his father heard him recite the Bismillah audibly in salah, he said, ‘O my son, this is something new (bid’ah). Keep away from innovation.’ Ibn Abdullah said, “I did not find any of the sahabah more against innovation in Islam than my father.’ He (Abdullah) said, “I offered salah with the Prophet (SAW) and with Abu Bakr (RA)Umar (RA) and Uthman (RA). None of them said the Bismillah in a loud voice. So, when you offer salah, do not recite it loudly, and begin the recital with al-Fatihah.”
