Hadith 17:115
Al-Fadl ibn Dukayn narrated to us, from Bashir ibn Sulayman, from Mujahid, who said: We were sitting with Abdullah ibn Amr, and he said: "I heard the Messenger of Allah (peace and blessings of Allah be upon him) enjoining [good treatment of] the neighbor, until we feared—or thought—that he would make him an heir."
حدثنا الفضل بن دكين عن بشير بن سليمان عن مجاهد قال كنا جلوسا عند عبد الله بن عمرو فقال إني سمعت رسول الله صلى الله عليه وسلم يوصي بالجار حتى خشينا أو رأينا أنه سيورثه
