There is no re birth but resurrections or return to this life which known as Raj'ah رجعة.
Raj'ah is the return of best servants of Allah and worst enemies of Allah to this life again to witness the victory of Islam and the punishment of its enemies. It is mentioned in Quran ( Sura Ghaafir, verse 11).
Imam Hussain (AS) will come back to this life in Raj'ah.
