Sabi bin Mabad reported,

I was a Christian Arabi man, then I embraced Islam. I went to a man from my clan named Hudhaym bin Tarmala and said to him, "My good man, I am eager for jihad, but I have found that Hajj and Umrah are prescribed upon me. How can I combine them both?"He said, "Combine them and sacrifice whatever sacrificial animal is readily available."So I entered the state of ihram for both of them together. When I reached al-Udhayb, Salman bin Rabia and Zayd bin Sawhan met me while I was calling the talbiyah for both of them together. One of them said to the other, "This man is no more knowledgeable than his camel."It felt as though a mountain had been thrown upon me. I went to Umar bin Khattab and said to him, "Commander of the Believers, I was a Christian Arabi man, then I embraced Islam, and I am eager for jihad. I found that Hajj and Umrah are prescribed upon me, so I went to a man from my people, and he said to me, 'Combine them and sacrifice whatever sacrificial animal is readily available.' So I entered ihram for both of them together."Umar said to me, "You have been guided to the Sunnah of your Prophet ﷺ."

عن الصبي بن معبد قال

كنت رجلا أعرابيا نصرانيا فأسلمت، فأتيت رجلا من عشيرتي يقال له هذيم بن ترملة فقلت له: يا هناه إني حريص على الجهاد وإني وجدت الحج والعمرة مكتوبين علي فكيف لي بأن أجمعهما؟ قال: اجمعهما واذبح ما استيسر من الهدي فأهللت بهما معا، فلما أتيت العذيب لقيني سلمان بن ربيعة وزيد ابن صوحان- وأنا أهل بهما جميعا- فقال أحدهما للآخر: ما هذا بأفقه من بعيره. قال: فكأنما ألقي علي جبل حتى أتيت عمر بن الخطاب فقلت له: يا أمير المؤمنين إني كنت رجلا أعرابيا نصرانيا، وإني أسلمت وأنا حريص على الجهاد، وإني وجدت الحج والعمرة مكتوبين علي، فأتيت رجلا من قومي، فقال لي: اجمعهما واذبح ما استيسر من الهدي، وإني أهللت بهما معا، فقال لي عمر رضي الله عنه: هديت لسنة نبيك ﷺ.
