1. Imam Ja’far Sadiq (a.s.) said, “When Allah resurrects a believer from his grave, He will also resurrect a person of his like, which will walk ahead of him. Whenever the believer will face a difficulty or fear on the Day of Judgment, this look-like will say, ‘Do not be sorrowful or fearful. There are glad-tidings for you from Allah’. It will continuously congratulate him till they reach the presence of Allah. His accounting of deeds will be easy and he will be ordered to enter Paradise and that look-alike will follow him. He will say to that creature, ‘Peace be upon you, for you were there with me in my grave and you are such a nice thing to come out of my grave that you are continuously giving me happiness since the time I saw you. Tell me who are you?’ It will reply, ‘I am the happiness that you gave to a believing brother in the world. Allah created me of that to give you glad-tidings’.”
