Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to say: Whoever swears an oath and then firmly maintains it, then breaks the oath, must free a slave or feed ten needy people. And whoever swears an oath and does not firmly maintain it, then breaks the oath, must feed ten needy people, giving each needy person one mudd of wheat. If he is not able to do so, then he must fast for three days.

Sulayman bin Yasar said that I saw people, when they would give the expiation for an oath, they used to give each poor person one mudd of wheat with the smaller mudd, and they considered that sufficient.

Imam Malik, may Allah have mercy on him, said: Whoever gives clothing to the poor as expiation for an oath, if he gives to poor men, giving one garment to each is sufficient, and if he gives to women, he should give two garments: a shirt and a head covering, which is called a khimar, because prayer is not valid with less than this.

When Abdullah bin Umar (may Allah be pleased with them both) would give the expiation for his oath, he would feed ten needy people, and he would give each needy person one mudd of wheat, and when he would swear the same oath multiple times, he would free as many slaves.
