´It was narrated from Muhammad bin 'Abdullah bin Al-Harith bin Nawfal bin Al-Harith bin 'Abdul-Muttalib that:` 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."

(1) Due to the command of Umar radi Allahu anhu, many people became mistaken and considered it a legal (shar‘i) matter, but the Companions and, later, the noble Imams clarified that tamattu‘ is legally permissible; in fact, according to many Imams, it is superior.
(2) If the statement of the ruler of the time or anyone else is contrary to the Shari‘ah and it is intended to refute it, then it should be done in the best manner, which is more effective and in which he does not feel insulted.

´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."
