The eighth Imam, His Eminence, Reza (a.s.) asked a person:
“What is the sign of Imamate according to you?”
He replied: “It is that a person should inform of unseen
matters, he should enliven and give death.”
Imam (a.s.) said: “Thus, I do all this. As for what you have concealed is five dinars. Your wife is also dead since one year. I enlivened her at this moment and she will remain with you for a year.”
The same thing happened and the destiny of that woman also became as the Imam had said
