The pilgrim should return to Mina and spend there the days of Tashreeq (i.e. the 11^th 12^th and 13^th days of Dhul-Hijjah).

 During each day, and after Dhuhr prayer until the midnight, the pilgrim stones the three stone  pillars called “Jamrat”: The smaller, the medium and Jamrat Al-Aqabah, glorifying Allah “Allah-u-Akbar “with each throw of the seven pebbles stoned at each pillar. 

These pebbles are picked up in Mina.  A pilgrim may leave Mina to Makkah on the 13^th of Dhul-Hijjah or on the 12^th if he wishes, there is no blame on him if he chooses the latter, but he has to leave before sunset if not he must stay in Mina till he throws the pebbles the next day (13^th).

Farewell Tawaf:

Farewell Tawaf is the final rite of Hajj.  It is to make another Tawaf around the Ka’bah.  Ibn Abbas said: “The people were ordered to perform the Tawaf around the Ka’bah as the last thing before leaving Makkah, except the menstruating women who were excused.”  (Bukhari)
