The Prophet ﷺ had two periods of silence; when he began his prayer and when he finished the recitation (of the Qur’an). He then narrated the tradition like the version of Yunus.
عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يَسْكُتُ سَكْتَتَيْنِ إِذَا اسْتَفْتَحَ وَإِذَا فَرَغَ مِنَ الْقِرَاءَةِ كُلِّهَا فَذَكَرَ مَعْنَى حَدِيثِ يُونُسَ
