[Machine] From the Messenger of Allah ﷺ , there was a pause when he would make takbeer (say "Allahu Akbar") and a pause when he finished reciting the Surah. Imran bin Husain was disturbed by this, so they wrote to Ubay bin Ka'b about it. Ubay wrote back, confirming that Samurah had indeed memorized the narration from the Messenger of Allah ﷺ .
عَنْ رَسُولِ اللهِ ﷺ سَكْتَةً إِذَا كَبَّرَ وَسَكْتَةً إِذَا فَرَغَ مِنْ قِرَاءَةِ السُّورَةِ» فَعَابَ ذَلِكَ عَلَيْهِ عِمْرَانُ بْنُ حُصَيْنٍ فَكَتَبُوا إِلَى أُبَيِّ بْنِ كَعْبٍ فِي ذَلِكَ فَكَتَبَ أُبَيٌّ صَدَقَ سَمُرَةُ وَيَقُولُ إِنَّ سَمُرَةَ حَفِظَ الْحَدِيثَ عَنْ رَسُولِ اللهِ ﷺ
