Suhayl bin Abi Salah سهيل بن أبي صالح · The Book of Hajj

Allah, Most High, has decreed Hajj for you. Al-Aqra' bin Habis At-Tamimi said: "Every year, O Messenger of Allah?" But he remained silent, then he said: "If I said yes, it would become obligatory, then you would not hear and obey. Rather it is just one Hajj."
