Those Who Do Not Say That "Bismilaahir-Rahmanir-Rahim" Should Be Said Aloud
Sunan Abi Dawud
حَدَّثَنَا هَنَّادُ بْنُ السَّرِيِّ، حَدَّثَنَا ابْنُ فُضَيْلٍ، عَنِ الْمُخْتَارِ بْنِ فُلْفُلٍ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أُنْزِلَتْ عَلَىَّ آنِفًا سُورَةٌ " . فَقَرَأَ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ { إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ } حَتَّى خَتَمَهَا . قَالَ " هَلْ تَدْرُونَ مَا الْكَوْثَرُ " . قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ . قَالَ " فَإِنَّهُ نَهْرٌ وَعَدَنِيهِ رَبِّي فِي الْجَنَّةِ " .
Anas b. Malik said: The Messenger of Allah (ﷺ) said: A surah has just been revealed to me. He then recited:”In the name of Allah, the Compassionate, the Merciful. Lo! We have given thee Abundance” until he finished it. Then he asked: Do you know what Abundance (al-Kawthar) is? They replied: Allah and His Apostle know it better. He said: It is a river of which my Lord, the Exalted, the Majestic has promised me to give in Paradise.
