Zakariyya came to Imam Ja'fer As-Sadiq (as) and said: "I was a Christian but have now become a Muslim." "It was the Qur'an that convinced me!"
Imam told Zakariyya:
"Indeed Allah has guided you to Islam and made your heart shine with it's light."
"But my parents are not Muslims, Ya Imam!" Zakariyya said.
Imam replied:
"Take care of your mother. Be good and kind to her..."
When he returned home he looked afetr his mother being even more gentle and kind to her than before. His mum noticed the change in her son's behaviour and said:
"What is the reason of you honouring me so much after you have become a Muslim?"
Zakariyya told her what Imam Ja'fer As-Sadiq (as) had said.
She replied:
"My son! Your religion is better than mine. Guide me so that I may become a Muslim."
Zakariyya taught her the basis of Islam and she bacame a Muslim. She offered the Dhuhr, Asr, Maghrib abd Isha Salaa of that day as taught to her by her son and died a Muslim at midnight on that day.
