Aabaan Ibn Taghlib narrates:
I was engaged in the circumambulation of the Ka’bah in the company of Imam Sadiq (peace be upon him) when one of my friends asked me to move to a side and listen to his request. Not wanting to leave the company of the Imam (peace be upon him), I ignored him and disregarded his request.
In the next round around the Ka’bah that person signaled me to come towards him; this time however the Imam (peace be upon him) happened to see him and so asked me: O’ Aabaan! Does he have some work with you? I replied in the affirmative, whereupon the Imam (peace be upon him) inquired: Who is he? I said: One of my friends. The Imam (peace be upon him) further inquired: Is he also a Mu’min and a Shiite? I replied: Yes.Hearing this, the Imam (peace be upon him) instructed: Go to him and fulfill his desire.
Should I discontinue my circumambulation? I queried. He (peace be upon him) replied: Yes. I asked: Is it permissible to discontinue even the obligatory circumambulations and leave them midway if it is for the purpose of fulfilling the needs of a Mu’min? He (peace be upon him) replied: Yes.
I halted my circumambulation and proceeded towards the man. After assisting the person, I returned to the Imam (peace be upon him) and requested him to inform me of the rights of a Mu’min upon another Mu’min. ( Shanidani-ha-e-Taareekh, pg. 69; Mahajjah al-Baidhaa, vol. 3, pg. 356. )
