as salaamu alaykum
may this reach you in good health and imaan,
My father is a christian and his sister died some years ago. She was shot and later died from the wound. My father had argument with her long ago and stopped talking with her. After she died he felt sad that he didnt say good bye to her and that she didnt leave on good terms. He told me that he had a dream where they were in an arcade and he saw her. They were speaking about their issues and he said he never got to say good by. And she said ‘all is good’. My question is if its possible for the soul of non muslims after thier death to meet others in dreams … i was wondering because i thought she would be questioned in the grave.
Wa alaykumus sulaam
ALLAH TA’AALA HAS MENTIONED IN THE QUR’AAN IN SURAH ISRAA/BANI ISRAAIL IN AAYAH NO 85
وَيَسْأَلُونَكَ عَنِ ٱلرُّوحِ قُلِ ٱلرُّوحُ مِنْ أَمْرِ رَبِّي وَمَآ أُوتِيتُم مِّنَ ٱلْعِلْمِ إِلاَّ قَلِيلاً }
And they will question you, that is, the Jews, concerning the Spirit, from which the body receives life. Say, to them, ‘The Spirit is of the command of my Lord, that is, [it belongs to] His knowledge, about which you know not. And of knowledge you have not been given except a little’, relative to His knowledge, exalted be He.
Since your question is concerning the souls , i rather not take the liberty of answering it from my opinion , rather we leave it as is. Although many books have been written on this topic by the likes of ibn qayyim and suyuti rahimahummallah yet they are insufficient in the matters of the soul. Allah has declared that you have only been given very little knowledge concerning it.
What we are aware of is that the kuffar recieve punishment in the grave daily , morning and evening as established from both he qur’aan as well as the ahaadeeth. As mufti shihab advised that this could be due to the constant thought your father had concerning the dispute and the feeling he feels of not patching up. Sometimes it so happens that what one thinks of in the day , He dreams about at night.
