Swear truthfully while taking an oath .

This hadith is about the importance of swearing by Allah when taking an oath. It was narrated that Rifa'ah bin 'Arabah A-Juhani said that the Messenger of Allah used to swear by saying "By the One in Whose Hand is my soul". This shows us how important it is to be sincere and truthful when making a promise or taking an oath. We should always remember that we are accountable for our words and actions before God and should strive to be honest with ourselves and others. By swearing by God, we are reminded of this responsibility and can ensure that our promises are kept.
