عن عامر بن واثلة

أن نافع بن عبد الحارث لقي عمر بعسفان، وكان عمر يستعمله على مكة، فقال: من استعملت على أهل الوادي؟ فقال: ابن أبزى. قال: ومن ابن أبزى؟ قال: مولى من موالينا. قال: فاستخلفت عليهم مولى؟ قال: إنه قارئ لكتاب الله عز وجل، وإنه عالم بالفرائض. قال عمر: أما إن نبيكم قد قال: إن الله يرفع بهذا الكتاب أقواما ويضع به آخرين.
