(22) باب تَرْكِ الْجَهْرِ بِـ { بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ }
Ibn Abdullah bin Mughaffal said:
"If Abdullah bin Mughaffal heard any one of us recite: 'In the Name of Allah, the Most Gracious, the Most Merciful', he would say: 'I prayed behind the Messenger of Allah (ﷺ) and behind Abu Bakr and behind Umar-may Allah be pleased with them both- and I did not hear any of them recite: 'In the Name of Allah, the Most Gracious, the Most Merciful."
