Returning to One's Home on the Eleventh Day Before Completing Hajj

Question:
He says: Last year, my brother and a colleague of his were there on the eleventh day, and they returned to Riyadh. What is required of him now, given that he wants to perform Hajj?

Answer:
This is one who has not completed his Hajj. He has not completed his Hajj. He should not return to Riyadh except on the twelfth day, after he has stoned the pillars in the afternoon and performed the farewell circumambulation, and then he returns to his home. This is if he hastens. But on the eleventh day, the twelfth and thirteenth days remain for him, for the one who delays. In that case, he has left off some of the obligatory acts of Hajj: he left off staying overnight in Mina on the night of the twelfth, he left off the farewell circumambulation because it is not valid except after the completion of the acts of Hajj, and he left off stoning the pillars.
All of these are obligatory acts. So for every obligatory act, he owes a ransom sacrifice, which he slaughters in Makkah and distributes to the poor. And he has committed a sin by this action and by his neglect of his rituals. Why did he not ask the scholars of knowledge at the proper time so that he would proceed with knowledge? Yes.
