The Rulings on Oaths and Conditioning Them on Allah’s Will?

The Shaykh : And if you take an oath, for example, if a person says, "By Allah, I will visit so-and-so today," and the day passes and he does not visit him, he must pay the expiation for an oath. But if he says, "By Allah, I will visit so-and-so today, if Allah wills," and he does not visit him, he owes nothing. Even though many people nowadays overlook this. They take oaths without saying "if Allah wills." And when they say "if Allah wills," they gain two great benefits: The first benefit is that Allah will facilitate for them what they swore to, as the Prophet (peace and blessings be upon him) said in the story of Sulayman: .
The second is that if he breaks the oath and does not fulfill it, he does not have to pay an expiation. Allah the Exalted said, returning to the verse: . "Duhaa" means its rising in the horizon until the time of Duhaa arrives. And this is undoubtedly one of the great signs of Allah.
