Oaths that require expiation

Question:
A message was sent from the Holy City of Madinah by a listener there, saying: Abu Mihad, Abu Mihad asks Your Eminence about the oaths that require expiation? May Allah reward you with good.

Answer:
Oaths are those made by a servant regarding future matters: "By Allah, I will not eat such-and-such," "By Allah, I will not visit so-and-so," "By Allah, I will not do such-and-such," or "By Allah, I will certainly do such-and-such," or "I will certainly speak to him," things that are in the future. If he contradicts the oath, expiation becomes obligatory upon him. For example, if he says, "By Allah, I will not visit so-and-so," and then visits him, he owes expiation. Or if he says, "By Allah, I will not drink this thing," and then drinks it, expiation becomes obligatory upon him. Or if he says, "By Allah, I will not travel today," and then travels, he owes expiation, and so on. Yes.
As for the past, this is called lying. If he says regarding the past, "By Allah, I did not do such-and-such," and he is lying, he commits a sin, and he must repent to Allah. Or if he says, "By Allah, I did not visit so-and-so," and he is lying, he must repent, and there is no expiation for it. Or if he says, "By Allah, I did not deal with so-and-so," or "I did not give him such-and-such," and he is lying, he must repent. Yes, and there is no expiation for it. Yes.

The presenter : May Allah reward you with good.
