Does a triple divorce befall the wife if the husband swore that she should not sit with a specific sheikh, and she sat with him, knowing that the sheikh said it does not count because she did not sit in his house?

Swearing by divorce and making it conditional leads to divorce upon the fulfillment of the condition, according to the majority of scholars. If divorce is intended, then uttering "talaq three times" results in a triple divorce. However, Sheikh al-Islam Ibn Taymiyyah differed, holding that swearing by divorce, when not intended to effect divorce but rather for threat or emphasis, falls under the ruling of an oath by Allah, and thus requires an expiation for an oath. He also held that uttering "talaq three times" counts as a single divorce. The spouses must consult people of knowledge to inquire about the husband's intention when swearing by divorce, as intention is the basis of oaths. If he had no intention, then what matters is the reason that led him to swear. It is advisable not to swear by divorce, as it is among the oaths of the dissolute, and grave consequences may ensue.
