"We used to greet the Prophet ﷺ with salam and he would return our salam, until we came back from the land of Ethiopia. I greeted him with salam and he did not return my greeting,a nd I started to wonder why. So I sat down; and when he finished praying, he said: 'Allah (SWT) decrees what He wills, and He has decreed what we should not speak during the prayer.'"  

كُنَّا نُسَلِّمُ عَلَى النَّبِيِّ ﷺ فَيَرُدُّ عَلَيْنَا السَّلاَمَ حَتَّى قَدِمْنَا مِنْ أَرْضِ الْحَبَشَةِ فَسَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَىَّ فَأَخَذَنِي مَا قَرُبَ وَمَا بَعُدَ فَجَلَسْتُ حَتَّى إِذَا قَضَى الصَّلاَةَ قَالَ إِنَّ اللَّهَ ﷻ يُحْدِثُ مِنْ أَمْرِهِ مَا يَشَاءُ وَإِنَّهُ قَدْ أَحْدَثَ مِنْ أَمْرِهِ أَنْ لاَ يُتَكَلَّمَ فِي الصَّلاَةِ  

We used to salute during prayer and talk about our needs. I came to the Messenger of Allah ﷺ and found him praying. I saluted him, but he did not respond to me. I recalled what happened to me in the past and in the present. When the Messenger of Allah ﷺ finished his prayer, he said to me: Allah, the Almighty, creates new command as He wishes, and Allah, the Exalted, has sent a fresh command that you must not talk during prayer. He then returned my salutation.  

كُنَّا نُسَلِّمُ فِي الصَّلاَةِ وَنَأْمُرُ بِحَاجَتِنَا فَقَدِمْتُ عَلَى رَسُولِ اللَّهِ ﷺ وَهُوَ يُصَلِّي فَسَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَىَّ السَّلاَمَ فَأَخَذَنِي مَا قَدُمَ وَمَا حَدُثَ فَلَمَّا قَضَى رَسُولُ اللَّهِ ﷺ الصَّلاَةَ قَالَ إِنَّ اللَّهَ يُحْدِثُ مِنْ أَمْرِهِ مَا يَشَاءُ وَإِنَّ اللَّهَ جَلَّ وَعَزَّ قَدْ أَحْدَثَ مِنْ أَمْرِهِ أَنْ لاَ تَكَلَّمُوا فِي الصَّلاَةِ فَرَدَّ عَلَىَّ السَّلاَمَ

I greeted him with salam and he did not return my greeting,a nd I started to wonder why. So I sat down; and when he finished praying, he said: 'Allah (SWT) decrees what He wills, and He has decreed what we should not speak during the prayer.'" (Using translation from Nasāʾī 1221)   

كُنَّا نُسَلِّمُ عَلَى النَّبِيِّ ﷺ إِذْ كُنَّا بِمَكَّةَ قَبْلَ أَنْ نَأْتِيَ أَرْضَ الْحَبَشَةِ فَلَمَّا قَدِمْنَا مِنْ أَرْضِ الْحَبَشَةِ أَتَيْنَاهُ فَسَلَّمْنَا عَلَيْهِ فَلَمْ يَرُدَّ فَأَخَذَنِي مَا قَرُبَ وَمَا بَعُدَ حَتَّى قَضَوْا الصَّلَاةَ فَسَأَلْتُهُ فَقَالَ إِنَّ اللهَ ﷻ يُحْدِثُ فِي أَمْرِهِ مَايَشَاءُ وَإِنَّهُ قَدْ أُحْدِثَ مِنْ أَمْرِهِ أَنْ لَا نَتَكَلَّمَ فِي الصَّلَاةِ  

[Machine] Abdullah, we used to greet the Prophet ﷺ and he would respond to us during prayer. But when we came from the land of Abyssinia, I greeted him and he didn't reply. He grabbed me and held me tightly until he finished praying. I said to him, "You used to respond to us." He ﷺ said, "Indeed, Allah speaks whatever He wills, and He has ordained that you do not speak during prayer."  

عَبْدُ اللَّهِ كُنَّا نُسَلِّمُ عَلَى النَّبِيِّ ﷺ فَيَرُدُّ عَلَيْنَا يَعْنِي فِي الصَّلَاةِ فَلَمَّا أَنْ جِئْنَا مِنْ أَرْضِ الْحَبَشَةِ سَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيَّ فَأَخَذَنِي مَا قَرُبَ وَ بَعُدَ فَجَلَسْتُ حَتَّى قَضَى الصَّلَاةَ قُلْتُ لَهُ إِنَّكَ كُنْتَ تَرُدُّ عَلَيْنَا فَقَالَ ﷺ «إِنَّ اللَّهَ يُحْدِثُ مَا شَاءَ وَقَدْ أَحْدَثَ مِنْ أَمْرِهِ قَضَاءً أَنْ لَا تَكَلَّمُوا فِي الصَّلَاةِ»  

[Machine] Ibn Masud, we used to say salaam to the Prophet ﷺ while he was praying, and he would respond to us. But when I returned from Abyssinia, I said salaam to him and he did not respond to me. He then started narrating to me everything, whatever had passed and what happened in my absence. Then I waited for him until he finished his prayer, and I mentioned that incident to him. He said: Verily, Allah speaks whatever He wills and He has spoken to me. And He informed me that I should not speak during the prayer.  

ابْنُ مَسْعُودٍ كُنَّا نُسَلِّمُ عَلَى النَّبِيِّ ﷺ وَهُوَ فِي الصَّلَاةِ فَيَرُدَّ عَلَيْنَا فَلَمَّا جِئْتُ مِنْ أَرْضِ الْحَبَشَةِ سَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْنَا فَأَخَذَنِي مَا تَقَدَّمَ وَمَا تَأَخَّرَ ثُمَّ انْتَظَرْتُهُ فَلَمَّا قَضَى صَلَاتَهُ ذَكَرْتُ ذَلِكَ لَهُ فَقَالَ إِنَّ اللهَ يُحَدِثُ مِنْ أَمْرِهِ مَا شَاءَ وَإِنَّهُ قَضَى أَوْ قَالَ أَحْدَثَ أَنْ لَا تَكَلَّمُوا فِي الصَّلَاةِ  

[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

كُنَّا نُسَلِّمُ فِي الصَّلَاةِ وَنَأْمُرُ بِحَاجَتِنَا فَقَدِمْتُ عَلَى رَسُولِ اللهِ ﷺ وَهُوَ يُصَلِّي فَسَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيَّ السَّلَامَ فَأَخَذَنِي مَا قَدُمَ وَمَا حَدُثَ فَلَمَّا قَضَى رَسُولُ اللهِ ﷺ الصَّلَاةَ قَالَ إِنَّ اللهَ يُحْدِثُ مِنْ أَمْرِهِ مَا يَشَاءُ وَإِنَّ اللهَ قَدْ أَحْدَثَ أَنْ لَا تَكَلَّمُوا فِي الصَّلَاةِ فَرَدَّ عَلَيَّ السَّلَامَ  

"كُنَّا نُسَلِّمُ عَلَى النَّبِىِّ ﷺ وَهُوَ فِى فَأخَذَنى الصَّلَاة، فَيَرُدُّ عَلَيْنَا، فَلَمَّا جئْتُ منْ أَرْضِ الْحَبَشَةِ سَلَّمْتُ عَلَيْهِ، فَلَمْ يَرُدَّ عَلَىَّ، فَأَحْزَنِّى مَا تَقَدَّمَ وَمَا تَأَخَّرَ، ثُمَّ انْتَظَرْتُهُ، فَلَمَّا قَضَى صَلَاتَهُ، ذَكَرْتُ ذَلِكَ لَهُ، فَقَالَ: إِنَّ الله يُحْدثُ منْ أَمْرِهِ يُسْرًا، وَمَا لَنا وَأَنَّهُ قَدْ قَضَى، - أَو قَالَ أَحْدَثَ - أَنْ لا تَكَلَّمُوا فِى الصَّلَاةِ".
