Keep your promises and commitments no matter what the cost may be.

This hadith is about making promises and commitments. It is narrated by Ayyub, who said that Al-Hasan made a promise that he would never return to something. This hadith teaches us the importance of keeping our promises and commitments, as it shows how seriously Al-Hasan took his word. We should strive to be like him in this regard, and make sure we keep our promises no matter what the cost may be. We should also remember that if we make a commitment or promise, it is important for us to keep it even if it becomes difficult or inconvenient for us at times.
