Abul Qassem Jaafar bin Masrur Al-Lahham narrated from HUSAIN (ASWS) bin Mohammad, from Ibrahim bin Mohammad, from Bilal, from Ibrahim bin Saleh Al-Anmati, from Abdul Samad, from JAAFAR BIN MOHAMMAD (ASWS) (6th Imam), from his FATHER (ASWS), from ALI bin HUSAIN (ASWS), from his father, who said:
The PROPHET (SAWW) was asked to explain this verse,
"Those who believe and do good, for them is bliss (TOUBA) and a beautiful place of return" (13:29)
The PROPHET (SAWW) explained that this verse refers to the COMMANDER OF THE BELIEVERS ALI (ASWS) , and that Touba is a tree in his house in Ferdous.
Every house in Paradise has a fruitful branch from this tree.
