وَعَنْهُ أَيْضًا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ وَاللَّهِ لَا يُؤْمِنُ وَاللَّهِ لَا يُؤْمِنُ وَاللَّهِ لَا يُؤْمِنُ قَالُوا وَمَا ذَاكَ يَا رَسُولَ اللَّهِ قَالَ الْجَارُ لَا يَأْمَنُ جَارُهُ بَوَائِقَهُ قَالُوا يَا رَسُولَ اللَّهِ وَمَا بَوَائِقُهُ قَالَ شَرُّهُ
It is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: By Allah! That man cannot be a believer, by Allah! That man cannot possess faith, by Allah! That person cannot be a true believer. The people asked: O Messenger of Allah! Who is he? He, peace and blessings be upon him, said: The neighbor whose neighbors are not safe from his evils. The people asked: O Messenger of Allah! What is meant by "bawa'iq"? He, peace and blessings be upon him, said: His evil.
