He then recited: In the Name of Allah, the Most Beneficent, the Most Merciful prolonging the pronunciation of 'In the Name of Allah, 'the most Beneficent,' and 'the Most Merciful. (Using translation from Bukhārī 5046)
سُئِلَ أَنَسُ بْنُ مَالِكٍ كَيْفَ كَانَتْ قِرَاءَةُ رَسُولِ اللهِ ﷺ؟ قَالَ كَانَتْ مَدًّا ثُمَّ قَرَأَ بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ يَمُدُّ بِسْمِ اللهِ وَيَمُدُّ الرَّحْمَنِ وَيَمُدُّ الرَّحِيمِ
