Ibn Umar (Allah be pleased with them) reported Allah's Apostle ﷺ having said this: When any one of you is invited to a wedding feast, he should accept that.
This hadith also reminds us that we should be grateful for any blessings or favors that come our way, even if it is something small like an invitation to a wedding feast. We must remember that Allah has blessed us with many things in life and we must show appreciation for these blessings by being thankful and accepting them with open arms whenever possible.
