Abu Hurairah (May Allah be pleased with him) reported:
The Prophet ﷺ said, "By Allah, he is not a believer! By Allah, he is not a believer! By Allah, he is not a believer." It was asked, "Who is that, O Messenger of Allah?" He said, "One whose neighbour does not feel safe from his evil".

[Al-Bukhari and Muslim].

Another narration of Muslim is: Messenger of Allah ﷺ said, "He will not enter Jannah whose neighbour is not secure from his wrongful conduct".

وعن أبي هريرة رضي الله عنه أن النبي ﷺ قال: " والله لا يؤمن، والله لايؤمن، والله لا يؤمن!" قيل: من يا رسول الله؟ قال: " الذي لا يأمن جاره بوائقه ! " ((متفق عليه)). وفي رواية لمسلم: " لايدخل الجنة من لا يأمن جاره بوائقه".
