Abul Hasan Ahmad bin Al-Hasan Al-Dhahhak Al-Razi narrated from Hamza bin Abdillah Al- Maleki, from Abdullah bin Mohammad Rasmoweyh, from Ibn Harma, from Anas bin Malik, who said:
The MESSENGER OF ALLAH (SWT) asked me to saddle his mule, so I did. Then the PROPHET (SAWW) rode and I followed him. When we arrived at the house of the COMMANDER OF THE BELIEVERS (ASWS), the PROPHET (SAWW) asked me to saddle ALI (ASWS) ’s mule, so I did.
The PROPHET (SAWW) and ALI (ASWS) …rode together and I was following them until they came to a green and beautiful land. Then a white cloud covered them so I went closer and I heard a loud voice saying:
“ASSALAAMU ALAIKUMA WA RAHMATULLAH WA BARAKATU.”
They answered the Salaam. Then Jibraeel came down, and then I could no longer see them. Then when Jibraeel went back up, I saw the PROPHET (SAWW) call ALI (ASWS) .
The PROPHET (SAWW) gave ALI (ASWS) an apple that had the following statement written on it with the power of ALLAH (SWT), “This is a present from the Predominant Lord to his WALI, ALI BIN ABI TALEB (ASWS).”
