Uthman bin 'Umar bin Fars عثمان بن عمر بن فارس · The Book of Hajj

during the year that Mu'awiyah bin abi sufyan performed Hajj, he heard Sa'd bin Abi Waqqas and Ad-Dahhak bin Qais talking about joining 'Umrah to Hajj (Tamattu) Ad-Dahhak said: "none does that but one who is ignorant of the ruling of Allah." Sa'd said: "What a bad thing to say, O son of my brother!" Ad-Dahhak said: "Umar bin Al-Khattab forbade that." Sa'd daid: "The Messenger of Allah did that and we did it with him."

"Abdullah, may Allah be pleased with him, said: "I have not failed to touch these two corners since I saw the Messenger of Allah touching them, the Yemeni Corner and Black Stone, either when it is difficult or when it is easy.'"

"We returned during the Hajj with the Prophet and some of us said that they had stoned (the Jamarat) with seven stones, and other said that they had done so with six, and no one denounced anyone else."
