Ritual 250

It is forbidden for a pilgrim in a state of ihram to quarrel with others, particularly to swear by Allah in order to prove something. Apparently, the prohibition is not exclusive to “La Wallah” (No, by Allah) or “Bala Wallah” (Yes, by Allah), but includes all types of swearing in the name of Allah in any language, even though it does not include la or bala. However, swearing by other than Allah is not taken into account.
