In the Name of Allah, the All-Merciful, the Mercy-giving

All praise is due to Allah. Peace and blessings be upon His Prophet Muhammad.

 

Ibn `Abbas reported that people (after performing Hajj rituals) started to go all directions, whereupon the Messenger of Allah (peace and blessings be upon him) said, “No one of you shall depart until the last thing he does is to go around the Sacred House.” (Muslim)

 

This hadith supports the opinion adopted by a group of scholars that Farewell Tawaf is obligatory and missing it requires an offering of sacrifice as redemption.

 

Thus, whenever one is about to leave Mecca after Hajj, he/she has to perform farewell tawaf. If one needs to leave Mecca for some reason with the intention of coming back to perform farewell tawaf, still he/she has to perform farewell tawaf first. If he/she departs without performing farewell tawaf and then comes back to perform it, this may remit the redemption.

 

Almighty Allah knows best.
