Muhammad bin Abdullah bin Al-Harith bin Nawfal narrated that:
He heard Sa'd bin Abi Waqas, and Ad-Dahhak bin Qais while they were mentioning Tamattu after Umrah until Hajj. Ad-Dahhak bin Qais said: No one does that except one who is ignorant of the order of Allah, Most High. Sa'd said: How horrible is it what you have said O my nephew! So Ad-Dahhak (bin Qais) said: Indeed Umar bin Al-Khattab has prohibited that. So Sa'd said: The Messenger of Allah did it, and we did it with him.
