Al-Tawalli is to love and respect the Ahlulbayt and al-Tabarri is to disassociate from the enemies of the Ahlulbayt.
The Holy Qur’an instructs Muslims to take as examples in their life the Prophet Muhammad (s.a.w) and the other noble persons, whom God has blessed, especially his family.
In this way, those who have strived for the cause of God, despite the difficult circumstances, are preserved in history and remembered by later generations who hope to emulate them. This is to ensure that the people of good are known and that Muslims will follow and love those whom Allah loves, that is the Prophet (s.a.w) and his Holy family.
Together with Tawalli, God has also commanded Muslims not to befriend or associate with those who are the enemies of Allah, those who are the enemies of the Prophet Muhammad (s.a.w) and his family. This is called al-Tabarri.
These are the tyrants and evil people of history who have fought against and persecuted the Prophets, the Imams and the faithful believers in Allah. This command forbidding Muslims from accepting wicked people as leaders and guardians establishes a distinguishing line which means good and evil can never be confused with each other.
