Hadith.2592 - Ibn Muskan narrated from Abu Basir, who said
I asked Abu Abdullah (as) about a Muhrim (one in the state of Ihram) who intends to perform a certain action, and his companions say to him, "By Allah (swt), do not do it." This person then replies, "By Allah (swt), I will do it," and they exchange such oaths repeatedly. Does this make him liable for what applies to one who disputes (jidal)?
Imam (as) said: "No, for his intention in this is to honor his brother. He is only liable if it involves disobedience to Allah (swt), the Almighty."
