Allah Almighty said:
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَدْخُلُوا بُيُوتًا غَيْرَ بُيُوتِكُمْ حَتَّىٰ تَسْتَأْنِسُوا وَتُسَلِّمُوا عَلَىٰ أَهْلِهَا ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ لَعَلَّكُمْ تَذَكَّرُونَ
O you who have faith, do not enter houses other than your own houses until you ascertain welcome and greet their inhabitants with peace. That is best for you, that perhaps you will be reminded.
Surat al-Nur 24:27
And Allah said:
فَإِذَا دَخَلْتُم بُيُوتًا فَسَلِّمُوا عَلَىٰ أَنفُسِكُمْ تَحِيَّةً مِّنْ عِندِ اللَّهِ مُبَارَكَةً طَيِّبَةً
When you enter houses, offer greetings of peace upon each other, a greeting from Allah, blessed and good.
Surat al-Nur 24:59
And Allah said:
وَإِذَا حُيِّيتُم بِتَحِيَّةٍ فَحَيُّوا بِأَحْسَنَ مِنْهَا أَوْ رُدُّوهَا ۗ إِنَّ اللَّهَ كَانَ عَلَىٰ كُلِّ شَيْءٍ حَسِيبًا
When you are greeted with a greeting, greet with one better than it or return it in a like manner.
Surat al-Nisa 4:86
And Allah said:
هَلْ أَتَاكَ حَدِيثُ ضَيْفِ إِبْرَاهِيمَ الْمُكْرَمِينَ إِذْ دَخَلُوا عَلَيْهِ فَقَالُوا سَلَامًا ۖ قَالَ سَلَامٌ قَوْمٌ مُّنكَرُونَ
Has there reached you the story of the honored guests of Abraham? When they entered upon him and greeted him with peace, he said: And for you peace, a people unknown.
Surat al-Dhariyat 51:24-25
Abdullah ibn Amr reported: A man asked the Prophet, “Which Islam is best?” The Messenger of Allah, peace and blessings be upon him, said:
تُطْعِمُ الطَّعَامَ وَتَقْرَأُ السَّلاَمَ عَلَى مَنْ عَرَفْتَ وَمَنْ لَمْ تَعْرِفْ
To feed the hungry and to greet with peace those you know and those you do not know.
And Ammar ibn Yasir said:
ثَلَاثٌ مَنْ جَمَعَهُنَّ فَقَدْ جَمَعَ الْإِيمَانَ الْإِنْصَافُ مِنْ نَفْسِكَ وَبَذْلُ السَّلَامِ لِلْعَالَمِ وَالْإِنْفَاقُ مِنْ الْإِقْتَارِ
Whoever has three qualities will have completed the faith: fairness from yourself to others, offering peace to the world, and spending in charity even while poor.
