It is reported, on the authority of Ayesha (R.A.) and lbn Umar (R.A.) that the messenger of Allah (S.A.W.) said "The Angel Jibra'il (A.S.) counselled me so frequently regarding the rights of the neighbour that I feared, he too would be declared an heir."
This hadeeth shows that Angel Jibra'il (A.S.) brought commandments from Allah, concerning the rights of the neighbour so frequently and stressed the need to be kind and courteous to him with such force and regularity that the Holy Prophet (S.A.W.) thought that the neighbour also will be made an heir i.e. just as parents, children and near relatives inherit the property left by the deceased, he thought that the neighbour, too, will be given a share in it.
Note:- The purpose of this hadeeth is not merely to state a fact, but rather it is most effective way of highlighting the importance of the neighbour to the Muslims.
