'Uqba ibn 'Abdullah ibn 'Amr who said, "While we were sitting with the Prophet, may Allah bless him and grant him peace, in the shade of a tree while travelling between Makka and Madina, a bedouin, who was an example of the coarsest and fiercest kind of people came up and said, 'Peace be upon you,' and they said, 'And upon you.'"  

عَنْ عَبْدِ اللهِ بْنِ عَمْرٍو قَالَ بَيْنَمَا نَحْنُ جُلُوسٌ عِنْدَ النَّبِيِّ ﷺ فِي ظِلِّ شَجَرَةٍ بَيْنَ مَكَّةَ وَالْمَدِينَةِ إِذْ جَاءَ أَعْرَابِيٌّ مِنَ أَجْلَفِ النَّاسِ وَأَشَدِّهِمْ فَقَالَ السَّلامُ عَلَيْكُمْ فَقَالُوا وَعَلَيْكُمُ  

Abu Jamra said, "I heard Ibn 'Abbas say when he was greeted, 'And upon you and the mercy of Allah.'"  

سَمِعْتُ ابْنَ عَبَّاسٍ إِذَا سُلِّمَ عَلَيْهِ يَقُولُ وَعَلَيْكَ وَرَحْمَةُ اللهِ  

Qayla reported that a mans aid, "Peace be upon you, may Allah bless him and grant him peace." He said, "And peace be upon you and the mercy of Allah."  

قَالَ رَجُلٌ السَّلاَمُ عَلَيْكَ يَا رَسُولَ اللهِ قَالَ وَعَلَيْكَ السَّلاَمُ وَرَحْمَةُ اللهِ  

Abu Dharr said, "I came to the Prophet, may Allah bless him and grant him peace, when he had finished his prayer. I was the first person to be greeted with the greeting of Islam. He said, 'And on you and the mercy of Allah. From where have you come?' I said, 'From Ghifar.'"  

عَنْ أَبِي ذَرٍّ قَالَ أَتَيْتُ النَّبِيَّ ﷺ حِينَ فَرَغَ مِنْ صَلاَتِهِ فَكُنْتُ أَوَّلَ مَنْ حَيَّاهُ بِتَحِيَّةِ الإِسْلاَمِ فَقَالَ وَعَلَيْكَ وَرَحْمَةُ اللهِ مِمَّنْ أَنْتَ؟ قُلْتُ مِنْ غِفَارٍ  

'A'isha reported, "The Messenger of Allah, may Allah bless him and grant him peace, said, ''A'ish! This is Jibril who sends you greetings.' I said, 'And peace be upon him and the mercy of Allah and His blessings. You see what I do not see." By that she meant the Messenger of Allah, may Allah bless him and grant him peace.  

قَالَ رَسُولُ اللهِ ﷺ يَا عَائِشُ هَذَا جِبْرِيلُ وَهُوَ يَقْرَأُ عَلَيْكِ السَّلاَمَ قَالَتْ فَقُلْتُ وَعَلَيْهِ السَّلاَمُ وَرَحْمَةُ اللهِ وَبَرَكَاتُهُ تَرَى مَا لاَ أَرَى تُرِيدُ بِذَلِكَ رَسُولَ اللهِ ﷺ  

Mu'awiya ibn Qurra said that his father said to him, "My son, when a man passes by you and says, 'Peace be upon you (plural).' Do not say, 'And on you (singular)' as if you were singling out that greeting out for him alone. Rather say, 'Peace be upon you (plural).'"  

قَالَ لِي أَبِي يَا بُنَيَّ إِذَا مَرَّ بِكَ الرَّجُلُ فَقَالَ السَّلاَمُ عَلَيْكُمْ فَلاَ تَقُلْ وَعَلَيْكَ كَأَنَّكَ تَخُصُّهُ بِذَلِكَ وَحْدَهُ فَإِنَّهُ لَيْسَ وَحْدَهُ وَلَكِنْ قُلِ السَّلامُ عَلَيْكُمْ
