Mua’wiyah Ibn Wahab narrates: “When we set out for Makkah, there was an old man with us who used to engage himself in acts of worship, but did not profess the Shi’ite faith. This old man was accompanied by his nephew, who was of the Shi’ites.
During the journey, the old man fell sick. I said to his nephew: “Why don’t you inform him of the true faith; it is possible that Allah may take him away from the world in the state of true faith and Wilayah.”
However, the other people advised him to leave the man alone and to let him die upon his own faith. However his nephew did not heed their advice. He went to his uncle and said: “O’ Uncle! After the death of the Noble Prophet (S), the people, with the exception of a handful who had adhered to Amirul Mo’minin (as), became apostates despite the fact that the Caliphate (of Amirul Mo’minin (as)) had already been stipulated by the Noble Prophet (S).”
Hearing these words, the old man heaved a sigh and said, “I accept this faith,” and then breathed his last.”
Mua’wiyah Ibn Wahab relates: “We entered Madinah and arrived before Imam Sadiq (as). ‘Ali Ibn Sari, one of our companions, related the incident of the old man’s repentance and his acceptance of Imamate just before his death, to the Imam (as) who said: “He is of the inmates of Paradise.”
‘Ali Ibn Sari remarked in astonishment: “The old man did not know anything about our faith and was totally ignorant of its laws and rulings; it was only when his soul was about to separate from his body that he accepted this faith!” The Imam (as) explained: “What (more) do you want of him? By Allah! He has (already) entered Paradise.”( Khazinatul Jawahir, Page 312; Rauďatul Anwar of Sabzwari )
