Sunan Ibn Majah, Volume 2, Book 5, Hadith 845 (DarusSalam) ⓘ

Samurah said: “I memorized two pauses in the prayer, a pause before reciting and a pause when bowing. ‘Imran bin Husain denied that, so they wrote to Al-Madinah, to Ubayy bin Ka’b, and he said that Samurah was speaking the truth.”

حَدَّثَنَا مُحَمَّدُ بْنُ خَالِدِ بْنِ خِدَاشٍ، وَعَلِيُّ بْنُ الْحُسَيْنِ بْنِ إِشْكَابَ، قَالاَ حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ يُونُسَ، عَنِ الْحَسَنِ، قَالَ قَالَ سَمُرَةُ حَفِظْتُ سَكْتَتَيْنِ فِي الصَّلاَةِ سَكْتَةً قَبْلَ الْقِرَاءَةِ وَسَكْتَةً عِنْدَ الرُّكُوعِ ‏.‏ فَأَنْكَرَ ذَلِكَ عَلَيْهِ عِمْرَانُ بْنُ الْحُصَيْنِ فَكَتَبُوا إِلَى الْمَدِينَةِ إِلَى أُبَىِّ بْنِ كَعْبٍ فَصَدَّقَ سَمُرَةَ ‏.‏
