Musnad Ahmad 83
Musnad `Umar b. al-Khattab (ra)
It was narrated from Abu Wa'il that as-Subayy bin Ma'bad was a Bedouin Taghlibi Christian who became Muslim. He asked: Which deed is best? He was told: Jihad for the sake of Allah, may He be glorified and exalted. He wanted to go for jihad, but it was said to him: Have you done Hajj? He said no. So it was said to him: Go for Haji and 'Umrah, then go for jihad. So he set out and when he was in al-Hawa'it, he entered ihram for both Haji and 'Umrah together, Zaid bin Soohan and Salman bin Rabee'ah saw him and said: He is more astray than his camel, or he is no more guided than his camel. He went to ‘Umar and told him what they had said. He said: You have been guided to the Sunnah of your Prophet (ﷺ) . Al-Hakam said: I said to Abu Wa'il. Did as-Subayy tell you that? He said: Yes
