It has been mentioned in vital narrations and in most authentic books that one day a man returned home from his work place, his wife saw him upset and gloomy, she asked the reason of his sadness which was clearly visible on his face, upon answering his wife, he said: today at work, I thought about the day of resurrection and hereafter and my place and position there, I thought if my place is hell or heaven, It was not clear for me, It extremely depressed me, and now I have come home with anxiety and want you to help me with this preoccupation that I have. The woman asked her husband if she could do anything for him,
The man answered: I want you to visit Hazrat Zahra (peace be upon her) because she is aware of the facts and ask her about my destiny and hereafter.
The woman went to Hazrat Zahra,s house and said the very sentences of her husband to Hazrat Zahra (peace be upon her), she responded the woman and said: tell your husband that if he is congruent with the holy Quran in his life affairs and has lived his life according to the holy Quran, he is certainly from those who will go to paradise otherwise he will be stricken to the punishment of the hell.
