Does the Prophet’s (peace and blessings be upon him) dispensation for al-‘Abbas to leave Mina without staying overnight indicate that staying overnight in Mina is not obligatory?

The questioner:
May Allah reward you, Your Eminence, father. Since the Prophet (peace and blessings be upon him) granted al-‘Abbas a dispensation to leave without staying overnight and did not require him to pay a blood sacrifice, does this indicate that the blood sacrifice is not obligatory?

The Shaykh:
What am I saying?

The questioner:
Say: Since the Prophet (peace and blessings be upon him) granted al-‘Abbas a dispensation to leave without staying overnight and did not require him to pay a blood sacrifice, does this indicate that the blood sacrifice is not obligatory?

The Shaykh:
It indicates that it is not obligatory for the one who has an excuse; the obligation of staying overnight is lifted from the one who has an excuse, and he does not have to pay a ransom. As for the one who has no excuse, if he leaves without staying overnight, he has to pay a ransom.
