[Machine] Sufyan, in his narration, raised it to the Prophet ﷺ and said, "Verily, circumambulating the Ka'bah is like prayer, except that you speak during it. So whoever speaks should speak only good." This is also narrated by Jarir. And Musa bin 'Ayyan, in his narration from the Prophet ﷺ , said, "Circumambulating the Ka'bah is a prayer, but Allah has allowed you to speak during it. So whoever speaks, let him speak only good." And it is mentioned in the narration of Al-Fudayl.  

سُفْيَانُ فِي رِوَايَتِهِ رَفَعَهُ إِلَى النَّبِيِّ ﷺ قَالَ إِنَّ الطَّوَافَ بِالْبَيْتِ مِثْلُ الصَّلَاةِ إِلَّا أَنَّكُمْ تَتَكَلَّمُونَ فِيهِ فَمَنْ تَكَلَّمَ لَا يَتَكَلَّمْ إِلَّا بِخَيْرٍ وَكَذَلِكَ فِي رِوَايَةِ جَرِيرٍ وَقَالَ مُوسَى بْنُ أَعْيَنَ فِي رِوَايَتِهِ عَنِ النَّبِيِّ ﷺ قَالَ الطَّوَافُ بِالْبَيْتِ صَلَاةٌ وَلَكِنَّ اللهَ أَحَلَّ لَكُمُ الْمَنْطِقَ فِيهِ فَمَنْ نَطَقَ فَلَا يَنْطِقْ إِلَّا بِخَيْرٍ وَبِمَعْنَاهُ فِي رِوَايَةِ الْفُضَيْلِ
