The questioner:
He says: Honorable Shaykh, may Allah grant you success, is it understood from the hadith of Salman that it is not permissible to swear oaths in buying and selling, even if the seller is truthful?
The Shaykh:
If he needs to swear, he swears; but if he does not need to, he does not swear, because if he swears without need, that is evidence of his laxity in his dealings.
