[Machine] We used to greet the Messenger of Allah ﷺ while he was praying, and he would respond to us. However, when we returned from Abyssinia, I greeted him and he did not respond to me. So, I said, "Oh Messenger of Allah, you used to respond to us." He replied, "The act of praying is sufficient occupation for me, not allowing me to respond."  

كُنَّا نُسَلِّمُ عَلَى رَسُولِ اللهِ ﷺ وَهُوَ يُصَلِّي فَيَرُدُّ عَلَيْنَا فَلَمَّا قَدِمْنَا مِنَ الْحَبَشَةِ سَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيَّ فَقُلْتُ يَا رَسُولَ اللهِ إِنَّكَ كُنْتَ تُرَدُّ عَلَيْنَا قَالَ كَفَى بِالصَّلَاةِ شُغُلًا لَفْظُ حَدِيثِ أَبِي عَبْدِ اللهِ  

[Machine] We used to greet the Prophet ﷺ while he was in prayer before we came to the land of Abyssinia (Ethiopia). He would respond to our greetings while he was in prayer. But when we returned from Abyssinia, I went to greet him and found him in prayer. I greeted him, but he did not respond to me. He grabbed me by the upper part of my garment and the lower part, sat me down until he finished his prayer. Then I went to greet him, and he said, "Verily, Allah, whose praise is glorified, speaks from His command whatever He wills. And verily, one of the things that Allah has forbidden is not to speak in prayer." This is all attributed to us based on strong evidence.  

كُنَّا نُسَلِّمُ عَلَى النَّبِيِّ ﷺ وَهُوَ فِي الصَّلَاةِ قَبْلَ أَنْ نَأْتِيَ أَرْضَ الْحَبَشَةِ فَيَرُدُّ عَلَيْنَا وَهُوَ فِي الصَّلَاةِ فَلَمَّا رَجَعْنَا مِنْ أَرْضِ الْحَبَشَةِ أَتَيْتُهُ لِأُسَلِّمَ عَلَيْهِ فَوَجَدْتُهُ يُصَلِّي فَسَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيَّ فَأَخَذَنِي مَا قَرُبَ وَمَا بَعُدَ فَجَلَسْتُ حَتَّى إِذَا قَضَى صَلَاتَهُ أَتَيْتُهُ فَقَالَ إِنَّ اللهَ جَلَّ ثَنَاؤُهُ يُحَدِثُ مِنْ أَمْرِهِ مَا يَشَاءُ وَإِنَّ مِمَّا أَحْدَثَ اللهُ أَنْ لَا تَكَلَّمُوا فِي الصَّلَاةِ وَقَدْ مَضَى فِي ذَلِكَ حَدِيثُ جَابِرِ بْنِ عَبْدِ اللهِ وَزَيْدِ بْنِ أَرْقَمَ وَذَلِكَ كُلُّهُ مَحْمُولٌ عِنْدَنَا عَلَى الْعَمْدِ
