Mohammad bin Abdillah bin Ubadillah bin Bohloul Al-MawALI narrated from Mohammad bin Hasan, from Isa bin Mihran, from Ubaidullah bin Musa, from KhALId bin Tahman Al-Khaffaf, from Saad bin Jonada Al-Awfi, from Zaid bin Arqam, from Abi Saeed Al-Khodri, who said:
The MESSENGER OF ALLAH (SWT) said, “ALI BIN ABI TALEB (ASWS) is the Master of Arabs.” So the people asked the PROPHET (SAWW), “Are you not the Master of Arabs?”
The PROPHET (SAWW) replied: I am the Master of human beings and ALI (ASWS) is the Master of Arabs. ALLAH (SWT) loves those who love ALI (ASWS) and follow him, and (ALLAH (SWT)) guides them to the right path. ALLAH (SWT) makes those who hate ALI (ASWS) and those who fight him deaf and blind.
ALI (ASWS) ’s HAQQ is my HAQQ, and following him is following me, except that there is no prophet after me. Those who abandon him abandon me, and those who abandon me abandon ALLAH (SWT).
I am the city of knowledge and ALI (ASWS) is the door of the city. How is it possible for anyone to be guided to Paradise except through this door? ALI (ASWS) is the best human being. Those who deny this are Kafers.
