Take your promises and commitments seriously; Be careful when making promises or taking on commitments; Have respect and reverence towards God SWT .

This hadith is about the importance of swearing an oath. It was narrated by AbuSa'id al-Khudri that when the Messenger of Allah (PBUH) swore an oath strongly, he said "No, by Him in Whose hand is the soul of Abul Qasim". This phrase is a way to swear an oath to emphasize its importance and seriousness. It shows us that we should take our promises and commitments seriously and not break them lightly. We should also be careful when making promises or taking on commitments as we are accountable for them before Allah SWT. Furthermore, this hadith also reminds us of how much respect and reverence we must have for Allah SWT as He holds all souls in His hands.
