Imam Baqir and Imam Jaffar Sadiq 's tradition on Love in Islam

Imam Baqir (a.s) said, "...Is religion anything but love? Haven't you seen the words of God, 'If you love God, follow me. God will love you and forgive you your sins for God is oft-forgiving, Most Merciful' ( Quran Ali-i- Imran 3:31) 
Haven't you heard what God told Muhammad, 'But God has endeared to you the faith, and has made it beautiful to your hearts, and He has made hateful to you unbelief, wickedness, and rebellion: such indeed are those who walk in righteousness.' ( Quran:Hujurat 49:7)
And God, the Almighty, said, '....  show their affection to such as came to them for refuge, and entertain no desire in their hearts for things given to the (latter), but give them preference over themselves, even though poverty was their (own lot). And those saved from the covetousness of their own souls,- they are the ones that achieve prosperity.'( Quran 59:9)

Therefore religion is as love, and love is as religion."
