"While I was praying, I said: Bismillahir-Rahmanir-Rahim "In the Name of Allah, the Merciful, the Beneficent." My father heard me and said: "O my son this is a newly invented matter, beware of the newly-invented.'" He (Ibn Abdullah) said: "I have not seen any one of the Companions of Messenger of Allah who hated a newly invented matter in Islam more than him. And he said: 'Ihave performed Salat with the Prophet, and with Abu Bakr, and Umar, and with Uthman. I did not hear any one of them saying it. So do not say it. When you are performing Salat say: Al-Hamdu lilahi Rabbil-Alamin "All praise is due to Allah the Lord of all that exists.'"  

سَمِعَنِي أَبِي وَأَنَا فِي الصَّلاَةِ أَقُولُ (بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ) فَقَالَ لِي أَىْ بُنَىَّ مُحْدَثٌ إِيَّاكَ وَالْحَدَثَ قَالَ وَلَمْ أَرَ أَحَدًا مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ كَانَ أَبْغَضَ إِلَيْهِ الْحَدَثُ فِي الإِسْلاَمِ يَعْنِي مِنْهُ قَالَ وَقَدْ صَلَّيْتُ مَعَ النَّبِيِّ ﷺ وَمَعَ أَبِي بَكْرٍ وَمَعَ عُمَرَ وَمَعَ عُثْمَانَ فَلَمْ أَسْمَعْ أَحَدًا مِنْهُمْ يَقُولُهَا فَلاَ تَقُلْهَا إِذَا أَنْتَ صَلَّيْتَ فَقُلِ (الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ)  

“I have rarely seen a man for whom innovation in Islam was harder to bear than him. He heard me reciting: ‘In the Name of Allah, the Most Gracious, the Most Merciful’ Bismillahir-Rahmanir-Rahim [1:1] and he said: ‘O my son, beware of innovation, for I prayed with the Messenger of Allah ﷺ, and with Abu Bakr, and with ‘Umar, and with ‘Uthman, and I never heard any of them saying this. When you (begin to) recite, say: ‘All the praises and thanks are to Allah, the Lord of all that exists.’ (Al-hamdu Lillahi Rabbil-‘Alamin).’” [1:2]  

وَقَلَّمَا رَأَيْتُ رَجُلاً أَشَدَّ عَلَيْهِ فِي الإِسْلاَمِ حَدَثًا مِنْهُ فَسَمِعَنِي وَأَنَا أَقْرَأُ {بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ} فَقَالَ أَىْ بُنَىَّ إِيَّاكَ وَالْحَدَثَ فَإِنِّي صَلَّيْتُ مَعَ رَسُولِ اللَّهِ ﷺ وَمَعَ أَبِي بَكْرٍ وَمَعَ عُمَرَ وَمَعَ عُثْمَانَ فَلَمْ أَسْمَعْ رَجُلاً مِنْهُمْ يَقُولُهُ فَإِذَا قَرَأْتَ فَقُلِ {الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ}
