Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:
Someone asked Messenger of Allah ﷺ: "Who is the best man?" He ﷺ answered, "A believer who strives in the Cause of Allah with his life and his wealth." The man asked: "Who is the next?" He said, "One who retires into a narrow valley and worships his Rubb."

Another narration is: Messenger of Allah ﷺ said, "One who fears Allah and safeguards people against his own mischief."

[Al-Bukhari and Muslim].

وعن أبي سعيد الخدرى رضي الله عنه قال: قال رجل: أى الناس أفضل يا رسول الله؟ قال: "مؤمن مجاهد بنفسه وماله فى سبيل الله" قال: ثم من؟ قال: " رجل معتزل فى شعب من الشعاب يعبد ربه" وفى رواية: "يتقي الله، ويدع الناس من شره" ((متفق عليه)).
