'Ja`far narrated from his father, Muhammad al-Baqir, that a man came to his grandfather, Zain al-`Abidin as-Sajjad, and said:
"Tell me about Abu Bakr!" He said, "You mean as-Siddiq?" The man said, "How do you call him as-Siddiq when he is against you, the Family of the Prophet ?"
He replied, "Woe to you. The Prophet called him as-Siddiq, and Allah accepted his title of as-Siddiq. If you want to come to me, keep the love of Abu Bakr and `Umar in your heart."'
