Ahmad bin Hasan bin Mohammad Al-Nishabouri narrated in his book, from Mohammad bin Husain Al-Ajari, from Jaafar bin Mohammad bin Al-‘Ezzi, from Qutaibah bin Saeed, from Jorair, from Moghira, from Mohammad bin Amr bin Abi Salama, from Ibn Abbas, who said:
The MESSENGER OF ALLAH (SWT) said:
ALI (ASWS) to me is like my blood is to my body. Those who accept his authority are rightly guided. Those who love him are on the right path. Those who follow him are the survivors.
Beware that ALI (ASWS) is one of the four in Paradise, who are HASAN (ASWS), HUSAIN (ASWS), ALI (ASWS) , and myself.
