7. NEIGHBOURS, RELATIVES AND GUESTS

t is the neighbors who know a person very well. They are close to us and very often interact with us. We know our neighbors better than the distant relatives. Usually they share our pleasure and sorrows. Islam gives utmost importance to the relation with the neighbors. The Holy Quran mentions about relation with the neighbors in the context of the verses on monotheism (i.e. oneness of God).
“Serve Allah, and join not any partners with Him; and do good- to parents, kinsfolk, orphans, those in need, neighbors who are near, neighbors who are strangers, the companion by your side, the wayfarer (ye meet), and what your right hands possess: For Allah loveth not the arrogant, the vainglorious.” (An-Nisa 36)
The Holy prophet says about the relation with neighbors: The Angel Gabriel (Jibril) kept recommending treating neighbors with kindness until I thought he would assign a share of inheritance.” (Bukhari)
The prophet in his farewell speech emphatically mentioned about the obligation to the neighbors. He has related it to the belief in religion. ‘Let any one believing in Allah and the Last Day honor the neighbor.’ (Bukhari/Muslim)
According to another report, the prophet said: “Let any one who believes in Allah and the Last Day, do not harm his neighbor.” 
Islam enjoins that whatever one wishes for her/him, should be wished for his neighbor also.
Prophet said: One will not become a true believer till what he wished for himself is wished for his neighbour also. In another report the prophet said by the name of Allah: “nobody will become a true believer until what is wished for him is wished for his neighbour also.” (Muslim)
The prophet told Abu Dharr: “O Abu Dharr! Whenever you prepare a broth, put plenty of water in it, and give some of it to your neighbors.” (Muslim)
The prophet declared: “He who feeds himself full stomach when his neighbour remains hungry is not a true believer.”
Abu Huraira reported: The Prophet said, “By Allah, he is not a believer! By Allah, he is not a believer! By Allah, he is not a believer.” It was asked, “Who is that, O Messenger of Allah?” He said: “One whose neighbour does not feel safe from his evil”
According to another report the prophet said: “He will not enter Jannah (Heaven) whose neighbour is not secure from his wrongful conduct.”
Prophet said that “the best of companions with Allah is the one who is best to his companions, and the best of neighbors to Allah is the one who is the best of them to his neighbour.”(Thirmidi)
Islam instructs that one should treat his neighbour very leniently, any harm done by them should be excused, and their sins should be pardoned. One should keep relation with the neighbour with faith in religion and make it stronger
