What is the tradition of Abul-Qasim that Prophet Muhammad (saw) mentioned regarding Hajj-at-Tamattu' and Hajj-Mabrur?
 Narrated Shu`ba:                     Abu Jamra Nasr bin `Imran Ad-Duba'i said, "I intended to perform Hajj-at-Tamattu` and the people advised me not to do so. I asked Ibn `Abbas regarding it and he ordered me to perform Hajj-at- Tammatu'. Later I saw in a dream someone saying to me, 'Hajj-Mabrur (Hajj performed in accordance with the Prophet's tradition without committing sins and accepted by Allah) and an accepted `Umra.' So I told that dream to Ibn `Abbas. He said, 'This is the tradition of Abul-Qasim.' Then he said to me, 'Stay with me and I shall give you a portion of my property.' " I (Shu`ba) asked, "Why (did he invite you)?" He (Abu Jamra) said, "Because of the dream which I had seen."
