Yahya related to me from Malik, from Ibn Shihab, from Said ibn al-Musayyab, that Umar ibn Abi Salama once asked Umar ibn alKhattab for permission to do umra in Shawwal. He gave him permission, so he did umra and then went back to his family, and he did not do hajj.
Muwatta Malik Book 20, Hadith 60
← Previous Hadith Yahya related to me from Malik, from Abd ar-Rahman ibn Harmala al-Aslami, that somebody asked Said ibn al-Musayyab, "Can I do umra before I do hajj?", and Said said, "Yes, the Messenger of Allah, may Allah bless him and grant him peace, did umra before doing hajj."

Muwatta Malik Book 20, Hadith 59 Next Hadith → Yahya related to me from Malik, from Hisham ibn 'Urwa, that his father would stop saying the talbiya when he entered the Haram, if he was doing 'umra.

Malik said that someone who went into ihram at at-Tanim should stop saying the talbiya when he saw the House.

Yahya said that Malik was asked where a man from the people of Madina, or elsewhere, who had begun doing umra at one of the mawaqit, should stop saying the talbiya, and he said, "Someone who goes into ihram at one of the mawaqit should stop saying the talbiya when he arrives at the Haram."

Malik added, "I have heard that Abdullah ibn Umar used to do that."
