Abul Hasan ALI bin Mohammad bin Alawy Al-Mostamli narrated from Abu Abdillah Mohammad bin Ahmad, from Hamdan bin Yahya, from Mohammad bin Sadaqa, from MUSA BIN JAAFAR (ASWS)(7TH IMAM), FROM JAAFAR BIN MOHAMMAD (ASWS), FROM HIS FATHER (ASWS), FROM ALI BIN HUSAIN (ASWS), FROM HIS FATHER (ASWS), who said:
The MESSENGER OF ALLAH (SWT) said:
When ALLAH (SWT) created Paradise, He ordered Paradise to decorate itself and it did. Then ALLAH (SWT) said to Paradise, “I swear to My Magnificence that I did not create you except for the believers. May there be bliss and happiness for you and your inhabitants!”
Then the PROPHET (SAWW) said to ALI (ASWS) , “O ALI (ASWS) , Paradise was not created except for you and your Shia.”
