Make expiration when you find something more beneficial or appropriate than your original decision .

This hadith explains the importance of making expiration for a dissolved oath. It was narrated by Abu Musa Al-Ash'ari who went to Allah's Messenger with a group of people from the tribe of Al-Ash'ari asking for mounts. The Prophet said he would not give them anything to ride, but after some time camels were brought to him and he ordered that they be given three camels. Some of them thought that Allah would not bless them because even though the Prophet had sworn he wouldn't give them mounts, he did in the end. When they returned to him with this concern, he explained that it was Allah who provided them with mounts and not himself; if ever he took an oath and then found something better than it, he would make expiration for his dissolved oath and do what is better instead. This teaches us that we should always strive to do what is best even if we have taken an oath or made a promise before hand; if we find something more beneficial or appropriate than our original decision, we should make expiration for our dissolved vow and choose what is best instead.
