5. Shaykh al-ʿAssāf says in Mukhtaṣar al-Iḥyāʾ:
   “As for the neighbour’s rights, neighbourliness demands more than merely withholding harm. It calls for enduring any harm that may come from him, treating him gently, and taking the initiative in doing good. One should greet him first with salām, visit him when he falls ill, console him in times of calamity, congratulate him on happy occasions, overlook his slips, refrain from peering into his house, avoid annoying him by letting water from one’s roof-spout pour into his property or by throwing dirt into his courtyard, not keep an inquisitive eye on whatever he carries into his home, conceal any private matters of his that become exposed, refrain from eavesdropping on his conversation, lower one’s gaze from his womenfolk, and look after the needs of his family when he is absent.”

6. He further states in Sharḥ al-Bulūgh:
   “The term ‘neighbour’ is inclusive of the Muslim, the unbeliever, the sinner, the friend, the enemy, the relative, and the stranger. Whoever combines all the qualities that call for loving good for him occupies the highest rank; whoever possesses most of them comes next, and so on down to the one who has but a single bond. Each person is therefore accorded his due according to his situation.”

Al-Ṭabarānī transmits on the authority of Jābir: “The non-Muslim neighbour has the right of neighbourliness; the Muslim neighbour has, along with neighbourliness, the right of Islam; and the Muslim neighbour who is also a relative enjoys three rights.”
