What is the meaning of argumentation (jidal) during Hajj? And do verbal altercations and anger between spouses during Hajj count as argumentation? And does argumentation spoil the reward of Hajj?

The forbidden argumentation during Hajj refers to disputes, contention, quarrels, and altercations, due to the evil and enmity they incite. Quarrels between spouses or others fall under the forbidden argumentation. However, Hajj is not invalidated by such acts, but rather its reward is diminished. As for studying knowledge and argumentation associated with enjoining good and forbidding evil, these are not part of the forbidden argumentation.
