Generally, neighbours are neighbours, Ramadan or no Ramadan. They are the people with whom one interacts closely, on a daily basis, in the same vicinity. Neighbours are co-inhabitants in the same residence, area, office, farm or market. Some of them are permanent. Others are temporary. This is not a matter of Ramadan alone. It is a general Islamic norm that all Muslims are supposed to follow.
In Islam, neighbours are so important that they are perceived as next of kin. And, Islam attaches so much respect to them like family members. According to Bukhari and Muslim, Prophet Muhammad (S.A.W) was reported to have once sworn by Allah three times saying: “He does not believe in Allah”!, He does not believe in Allah”!, He does not believe in Allah”! Whoever creates fear or restlessness in his neighbours”.
In another Hadith, also reported by Bukhari and Muslim, the Prophet was quoted as saying that “Whoever believes in Allah and the last day should treat his neighbour nicely and respect his guests”.
In the month of Ramadan, a good Muslim is expected to wear a new toga of sobriety and repentance. He should double his good deeds to his neighbours by extending generosity to them and by cultivating a new atmosphere of friendliness and trust with them. He should genuinely give them as much impression of love and brotherhood as he does with his consanguine relatives.
It does not matter whether the neighbours are Muslims or non-Muslims. Neither does it matter whether they are tribesmen or non-natives.
The Prophet did not discriminate in his Hadith when he was admonishing relationships with neighbours. And that is the inalienable position of Islam on interaction with people in the neighbourhood.
