Musannaf Ibn Abi Shaybah

Hazrat Kathir bin Jumhan narrates that we set out for Hajj and there was a man from the people of the mountains with us who had not performed Hajj before. He entered into the state of Ihram for both Hajj and Umrah together. Our companions considered this blameworthy and disliked it. We stayed near Hazrat Ibn Umar (may Allah be pleased with them). We said to him: There is a man from the people of the mountains with us who has not performed Hajj before, and he has entered into Ihram for both Hajj and Umrah together, and our companions have considered this blameworthy. What is its expiation? He replied: Its expiation is that he will return with double the reward, and you people with a single reward.
