Bukhari

Hadith Commentary:
(1)
In Islam, great importance is given to the neighbor, whether he is a Muslim or a disbeliever, a devout worshipper or a sinner and transgressor, a friend or an enemy, one’s own or a stranger, near or distant, well-wisher or ill-wisher. One is commanded to show goodwill to every type of neighbor.

Neighbors are of three types:
The first is one who is a polytheist (mushrik).
He has only one right.
The second is one who is a Muslim.
He has two rights:
One for being a neighbor and the other for being a Muslim.
The third is one who is also a relative.
He has three rights:
One for neighborhood, the second for Islam, and the third for kinship.
Even in the era of ignorance (Jahiliyyah), people used to fulfill the rights of neighbors; Islam has also maintained this.

From the aforementioned ahadith, the status of the neighbor is also evident. Whenever Abdullah ibn Amr radi Allahu anhuma would slaughter a goat at home, he would certainly send some of its meat to his Jewish neighbor’s house.
(Sunan Abi Dawud, Al-Adab, Hadith: 5152)
The reason for the narration of these ahadith is that an Ansari companion left his house to meet the Messenger of Allah sallallahu alayhi wa sallam and found him engaged in conversation with a man.
He sat and waited, and after seeing the Prophet sallallahu alayhi wa sallam standing for a long time, he began to feel compassion for him....
Finally, when the meeting took place, the Prophet said:
“Do you know who that was?” I said:
No.
He said:
“That was Jibril alayhis salam, who was advising me regarding the neighbor, to the extent that I thought he would make him my heir.”
(Musnad Ahmad: 32/5)
Although a neighbor does not inherit in financial inheritance, he is entitled to inheritance in intellectual legacy.
And Allah knows best.
