The Book of Asceticism · Hadith 116 (#Ḥadīth #2)

محمد بن الحسين عن محمد بن الفضيل عن إسحاق بن عمار قال:قال أبو عبد الله عليه السلام قال: رسول الله صلى الله عليه وآله: أعوذ بالله من جار سوء في دار إقامة تراك عيناه ويرعاك قلبه ان رآك بخير سائه وان رآك بشر سره

2.Muḥammad ibn al-Ḥusayn narrated from Muḥammad ibn al- Fuḍayl, from Isḥāq ibn ʿAmmār who said, “Abū ʿAbdillāh said, ‘The Messenger of Allah (ṣ) said, “I seek Allah’s protection from a bad neighbour in a residential abode – his eyes watch you and his heart scrutinises you. If he sees you [happy and] well, it upsets him and if he sees you in trouble, it pleases him.”’”
