Take responsibility for your actions and do what is right and just .

This hadith is about the importance of justice and fairness in Islam. It tells us that even if someone has not been born yet, they still deserve justice and fairness. In this case, Allah's Messenger imposed a blood-wit on the relatives of a murderer for killing her co-wife who was pregnant, despite one of them objecting to it. A blood wit is an amount paid by the killer or their family as compensation for taking someone else’s life. The Prophet also made an example out of this person by saying that he speaks like people from the desert do when they are trying to make excuses or avoid responsibility. This teaches us that we should always take responsibility for our actions and not try to make excuses or avoid doing what is right and just.
