Compiled by Imam Abu Dawud as-Sijistani
حَدَّثَنَا ابْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا سَعِيدٌ، بِهَذَا قَالَ عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ سَمُرَةَ، قَالَ سَكْتَتَانِ حَفِظْتُهُمَا عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم . قَالَ فِيهِ قَالَ سَعِيدٌ قُلْنَا لِقَتَادَةَ مَا هَاتَانِ السَّكْتَتَانِ قَالَ إِذَا دَخَلَ فِي صَلاَتِهِ وَإِذَا فَرَغَ مِنَ الْقِرَاءَةِ ثُمَّ قَالَ بَعْدُ وَإِذَا قَالَ { غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ } .
I remember from the Messenger of Allah (ﷺ) two periods of silence. Sa'id said: We asked Qatadah: What are those two periods of silence? He said: (one) when he began his prayer, and (one) when he finished the recitation. Then he added: When he finished reciting (the closing verse of the Fatihah): "Not of those with whom Thou art angry, nor of who go astray."
