Imam al-Sajjad (as): When Imam Ali Zayn al-Abidin (as) was approaching death, he hugged his son al-Baqir (as) close to his chest and said, ‘O my son, I am advising you of the same thing that my father advised me in his will when he was approaching death, and the same thing that he said his father advised him - O my son! Beware of wronging one who has no helper against you but Allah.’ al-Kāfī
