The hajj is valid as the pillars were performed. However, you have to slaughter two sheep for leaving the stoning on the 12 and for leaving the farewell Tawaf and you must feed a poor person for not spending the night of the 12 in Mina.

The farewell tawaf is mandatory for one who is leaving Mecca . Also it should be the last thing done. The flight bookings were made well in advance and now re scheduling isn’t available. ( since there is a great chance we might miss our flight) is it allowed that we do the stoning and leave for Jeddah straight from Mina or do the farewell tawaf on the 11th zilhujj.
