The Messenger of Allah ﷺ was asked, "Which speech is best?"He replied, "That which Allah has chosen for His angels," or he said, "for His servants, Glory be to Allah and praise be to Him."
أن رسول الله ﷺ سئل: أي الكلام أفضل؟ قال: ما اصطفى الله لملائكته أو لعباده: سبحان الله وبحمده.
Muslim narrated it in the Book of Remembrance and Supplication (2731), from Zuhayr bin Harb, who said, Habban bin Hilal narrated to us, Wahib narrated to us, Saeed Jariri narrated to us, from Abu Abdullah Jasri, from Abdullah bin Samit, from Abu Dharr, and he mentioned it.Regarding His saying, "Indeed, I know what you do not know" [Baqarah 2:30], this means that it may concern this succession of prophets and righteous people, and I know about them what you do not know. In this there is a restriction indicating that knowledge of the unseen belongs exclusively to Allah, the Exalted, and to no one else.
