عن أبي سعيد الخدري قال

لقيه-يعني ابن صياد- رسول الله ﷺ وأبو بكر وعمر في بعض طرق المدينة فقال له رسول الله ﷺ: أتشهد أني رسول الله؟ فقال هو: أتشهد أني رسول الله؟ فقال رسول الله ﷺ: آمنت بالله وملائكته وكتبه. ما ترى؟ قال: أرى عرشا على الماء، فقال رسول الله ﷺ: ترى عرش إبليس على البحر. وما ترى؟ قال: أرى صادقين وكاذبا أو كاذبين وصادقا فقال رسول الله ﷺ: لبس عليه دعوه.
