Keep your promises and honor your commitments .

This hadith is about the importance of fulfilling vows. It was narrated from Umar that he said he had vowed during the jahiliyyah to observe itikaf for one night in al-Masjid al-Haram. The Prophet Muhammad (PBUH) advised him to fulfill his vow, emphasizing the importance of keeping promises and honoring commitments. This hadith teaches us that we should be honest and sincere when making a promise or a commitment, and strive our best to keep it no matter what. We should also remember that Allah is always watching us, so we must be mindful of our words and actions at all times.
