Ibn Sayyad asked the Prophet ﷺ about the soil of Paradise. He replied, "It is fine white flour of pure musk."
أن ابن صياد سأل النبي ﷺ عن تربة الجنة؟ فقال: درمكة بيضاء مسك خالص.
Muslim narrated it in the Book of Tribulations (93:2928), on the authority of Abu Bakr bin Abu Shayba, who said, Abu Usama narrated to us, from Jareeri, from Abu Nadra, from Abu Saeed, and he related it. This is the sahih version, and careful consideration indicates that the Prophet ﷺ was the one being asked about hidden matters, not the one asking about them.However, Muslim placed before it (92:2928) what he narrated from Nasr bin Ali Jahdami, who said, Bishr, meaning Ibn Mufaddal, narrated to us, from Abu Maslama, from Abu Nadra, from Abu Saeed, who said, the Messenger of Allah ﷺ said to Ibn Sayyad, "What is the soil of Paradise?" ... and so on with the hadith. This version makes Ibn Sayyad the one being asked.Perhaps Muslim did this in consideration of its strength from the standpoint of hadith methodology, since it is stronger than the narration of Jareeri.
