‘Abdullaah ibn ‘Amr narrated that the Prophet of Allah, sallallaahu ‘alayhi wa sallam, said: “The best of companions are those who treat their companions in the best way, and the best of neighbors are those who treat their neighbors in the best way.”
Al-Ghazaali (a scholar) said: “The right of the neighbor is not merely to not harm him, rather it is to endure any harm from him. Nor is it enough to merely. endure his harm, rather one must respond to him in a gentle way, to greet him first, visit him if he becomes sick, to console him in a calamity, congratulate him in a good time, to share in his happiness if he is bestowed with something, to overlook his faults, to not look at his women, to protect his home if he is absent, to be kind to his children, and to guide him of what he is ignorant, both in religious and worldly affairs.”
