"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}  

[Machine] My father heard me reciting "In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, the Lord of all the worlds" (Chapter 1:2 of the Quran). After he finished, he said, "My son, beware of engaging in unnecessary discussions in Islam. I have prayed behind the Prophet ﷺ, Abu Bakr, Umar, and Uthman, and none of them used to begin their recitation with 'In the name of Allah, the Most Gracious, the Most Merciful.' I have never seen a person who disliked unnecessary discussions more than them."  

سَمِعَنِي أَبِي وَأَنَا أَقْرَأُ {بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ} [الفاتحة 2] فَلَمَّا انْصَرَفَ قَالَ يَا بُنَيَّ إِيَّاكَ وَالْحَدَثَ فِي الْإِسْلَامِ فَإِنِّي صَلَّيْتُ خَلْفَ رَسُولِ اللهِ ﷺ وَخَلْفَ أَبِى بَكْرٍ وَخَلْفَ عُمَرَ وَعُثْمَانَ فَكَانُوا لَا يَسْتَفْتِحُونَ الْقِرَاءَةَ بِبِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ وَلَمْ أَرَ رَجُلًا قَطُّ أَبْغَضَ إِلَيْهِ الْحَدَثُ مِنْهُ  

" عَنْ قَيْس بْنِ عَبَايَةَ قَالَ: حَدَّثَنِى ابْنُ عَبْدِ الله بْنِ مُغَفَّلٍ عَنْ أبَيِهِ قَالَ: وَلَمْ أَرَ رَجُلًا مِنْ أَصْحَابِ النَّبِىِّ - صَلَّى الله عَليْه وَسَلَّمَ - كَانَ أشَدَّ عَلَيْه حَدَثًا في الإِسْلَامِ مِنْهُ، قَالَ: سَمِعَنِى وَأَنَا أَقْرَأُ بِسْمِ الله الرَّحْمَنِ الرَّحِيمِ، قَالَ: يَا بُنَى إِيَّاكَ وَالْحَدثَ فَإنِّى صَلَّيْتُ خَلْفَ رَسُولِ الله ﷺ وَأبِى بَكْرٍ وَعُمَرَ وَعُثْمَانَ، فَلَمْ أَسْمَعْ مِنْهُمْ أَحَدًا يَقُولُ ذَلِكَ، إِذَا قَرَأتَ فَقلْ: الْحَمْدُ لله رَبِّ الْعَالَمِينَ".
