حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا إِسْمَاعِيلُ، عَنْ يُونُسَ، عَنِ الْحَسَنِ، قَالَ قَالَ سَمُرَةُ حَفِظْتُ سَكْتَتَيْنِ فِي الصَّلاَةِ سَكْتَةً إِذَا كَبَّرَ الإِمَامُ حَتَّى يَقْرَأَ وَسَكْتَةً إِذَا فَرَغَ مِنْ فَاتِحَةِ الْكِتَابِ وَسُورَةٍ عِنْدَ الرُّكُوعِ قَالَ فَأَنْكَرَ ذَلِكَ عَلَيْهِ عِمْرَانُ بْنُ حُصَيْنٍ قَالَ فَكَتَبُوا فِي ذَلِكَ إِلَى الْمَدِينَةِ إِلَى أُبَىٍّ فَصَدَّقَ سَمُرَةَ . قَالَ أَبُو دَاوُدَ كَذَا قَالَ حُمَيْدٌ فِي هَذَا الْحَدِيثِ وَسَكْتَةً إِذَا فَرَغَ مِنَ الْقِرَاءَةِ .
Narrated Samurah ibn Jundub: I remember two period of silence in prayer, one when the imam said the takbir; and one when he finished reciting the Fatihah and the surah when he was about to bow. But Imran ibn Husayn took it as something strange. So they wrote about it to Ubayy (ibn Ka'b) in Medina. He verified the statement of Samurah. Abu Dawud said: Humaid also narrated in this tradition the words "and one period silence when he finished the recitation (of the Qur'an)
