It wasnarrated that Jabir bin 'Abdullah said:
"We began our Talbiyahfor Hajj only with Allah's Messenger (ﷺ), and we did not mix itwith'Umrah. We arrived in Makkah when four nights of Dhul-Hijjahhadpassed, and when we had performed Tawaf around the Ka'bah andSa'ybetween Safa and Marwah, the Messenger of Allah (ﷺ)commanded us tomake it 'Umrah, and to come out of Ihram and haverelations with ourwives. We said: 'There are only five (days)until 'Arafah. Will we gout to it with our male organs drippingwith semen?' The Messenger ofAllah (ﷺ) said: 'I am the mostrighteous and truthful among you, andwere it not for the sacrificialanimal, I would have exited Ihram.'Suraqah bin Malik said: 'Isthis Tamattu' for this year only orforever?' He said: 'No, itis forever and ever.'"
