Hastening for the one who is unable to perform the stoning except after sunset

And among them: If a person hastens,Meaning: intending to leave Mina on the twelfth day and depart, but he is unable to perform the stoning except after sunset, is he required to remain in Mina and perform the stoning on the third day, or should he continue on his way?
He should continue on his way; because the man hastened and departed, and something prevented him from leaving before sunset, so he continues.
