"The Prophet would open his Salat with (Bismillahir-Rahmanir-Rahim)."

كَانَ النَّبِيُّ ﷺ يَفْتَتِحُ صَلاَتَهُ بِ (بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ )

[AI] The Mahdi prayed with us and recited "In the name of Allah, the Most Gracious, the Most Merciful" out loud. I asked him about that and he said, "My father told me, from his father, from his grandfather, from Ibn Abbas, that the Messenger of Allah ﷺ used to recite 'In the name of Allah, the Most Gracious, the Most Merciful' out loud."

صَلَّى بِنَا الْمَهْدِيُّ فَجَهَرَ بِبِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ فَقُلْتُ لَهُ فِي ذَلِكَ فَقَالَ حَدَّثَنِي أَبِي عَنْ أَبِيهِ عَنْ جَدِّهِ عَنِ ابْنِ عَبَّاسٍ أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَجْهَرُ بِبِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ

[AI] I prayed behind Umar ibn al-Khattab, and he recited aloud "In the name of Allah, the Most Gracious, the Most Merciful."

صَلَّيْتُ خَلْفَ عُمَرَ بْنِ الْخَطَّابِ فَجَهَرَ بِبِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ

[AI] Narrated by Abdullah ibn Umar, he used to open the mother of the Book (the Quran) with "In the name of Allah, the Most Gracious, the Most Merciful". This is the authentic narration (from the Prophet Muhammad) and it is stopped (meaning the narration ends here).

عَنْ عَبْدِ اللهِ بْنِ عُمَرَ كَانَ يَفْتَتِحُ أُمَّ الْكِتَابِ {بِبِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ} هَذَا هُوَ الصَّحِيحُ مَوْقُوفٌ

"The Prophet would open his Salat with (Bismillahir-Rahmanir-Rahim)." (Using translation from Tirmidhī 245)

كَانَ يَفْتَتِحُ الصَّلَاةَ بِ {بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ} [الفاتحة 1]

[AI] He used to say that the reading begins with "In the name of Allah, the Most Gracious, the Most Merciful" [Surah Al-Fatiha 1].

كَانَ يَقُولُ تُفْتَتَحُ الْقِرَاءَةُ بِ {بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ} [الفاتحة 1]

"عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى قَالَ: صَلَّيْتُ خَلفَ عُمَرَ فَجَهَرَ بِبِسْمِ الله الرَّحْمَنِ الرَّحِيمِ، وَكَان يَجْهرُ بِبِسْمِ الله الرَّحْمَنِ الرَّحِيمِ".

"عَنْ عَلِىٍّ قَال: كَان النَّبِىُّ ﷺ يَجْهَرُ في الْمكْتُوبَاتِ بِبِسْمِ الله الرَّحمنِ الرَّحيم".

"عَنْ عَبْدِ الكَرِيمِ أَبِى أُمَيَّةَ: أَنَّ أُبَىَّ بْنَ كَعْبٍ كَانَ يَفْتَتِحُ بِبِسْمِ الله الرَّحْمَنِ الرَّحِيمِ".

"عَنْ عَمْرِو بْن دينَارٍ أَنَّ ابْنَ عَبَّاس، وَابْنَ عُمَرَ كَانَا يَفْتَتِحَانِ {بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ} ".

" عَنِ ابْنِ عَبَّاس أنَّ رَسُولَ الله ﷺ صَلَّى فَجَهرَ: {بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ} ".

"عَنِ ابْنِ عُمَرَ أنَّ النَّبىَّ ﷺ كَانَ يَفْتَتِحُ الْقِرَاءَةَ بِبِسْم الله الرَّحْمنِ الرَّحِيمِ".
