The Prophet of Islam Muhammad Al-Mostafa (Peace be on him and his holy progeny) said regarding love for Imam Ali b. Abi Talib (peace be on him): ?The love of Ali ibn Abi-Talib is a tree whose root is in Paradise and its branches are in this world. Whoever from my community clings into any of its branches, it will reach them to Paradise. The hatred of Ali ibn Abi-Talib is a tree that its root is in hell and its branches are in this world. Whoever clings into any of its branches will enter into hell." Source: Beharul-Anwaar, vol.40 p.46
