Volume 003, Book 027, Hadith Number 001Narrated By Abu Huraira :
Allah's Apostle said, "(The performance of) 'Umra is an expiation for the sins committed (between it and the previous one). And the reward of Hajj Mabrur (the one accepted by Allah) is nothing except Paradise."
Volume 003, Book 027, Hadith Number 002Narrated By Ibn Juraij :
Ikrima bin Khalid asked Ibn 'Umar about performing 'Umra before Hajj. Ibn 'Umar replied, "There is no harm in it." 'Ikrima said, "Ibn 'Umar also said, 'The Prophet had performed 'Umra before performing Hajj.'"

"I asked Ibn 'Umar the same (as above)."
Volume 003, Book 027, Hadith Number 004Narrated By Mujahid :
Ursa bin AzZubair and I entered the Mosque (of the Prophet) and saw 'Abdullah bin Umar sitting near the dwelling place of 'Aisha and some people were offering the Duha prayer. We asked him about their prayer and he replied that it was a heresy. He (Ursa) then asked him how many times the Prophet had performed 'Umra. He replied, 'Four times; one of them was in the month of Rajab." We disliked to contradict him. Then we heard 'Aisha, the Mother of faithful believers cleaning her teeth with Siwak in the dwelling place. 'Ursa said, "O Mother! O Mother of the believers! Don't you hear what Abu 'Abdur Rahman is saying?" She said, "What does he say?" 'Ursa said, "He says that Allah's Apostle performed four 'Umra and one of them was in the month of Rajab." 'Aisha said, "May Allah be merciful to Abu 'Abdur Rahman! The Prophet did not perform any 'Umra except that he was with him, and he never performed any 'Umra in Rajab."
Volume 003, Book 027, Hadith Number 005Narrated By 'Ursa bin Az-Zubair :
I asked 'Aisha (whether the Prophet had performed 'Umra in Rajab). She replied, "Allah's Apostle never performed any 'Umra in Rajab."
Volume 003, Book 027, Hadith Number 006Narrated By Qatada :
I asked Anas how many times the Prophet had performed 'Umra. He replied, "Four times.
1. 'Umra of Hudaibiya in Dhi-l-Qa'da when the pagans hindered him;
2. 'Umra in the following year in Dhi-l-Qa'da after the peace treaty with them (the pagans);
3. 'Umra from Al-Jr'rana where he distributed the war booty." I think he meant the booty (of the battle) of Hunain. I asked, "How many times did he perform Hajj?" He (Anas) replied, "Once. "
