A lady asked Hazrat Amirul Momineen, Khalifatul Masih Vaa, “[…] Is it true that people at higher levels in Heaven will be able to meet those at lower levels than them, but those at lower levels will not be able to meet those at higher levels than them? […]”
Huzoor-e-Anwaraa replied:
“[…] Where the people of Paradise and the people of Hell are mentioned in the Holy Quran, there is also the mention of a barrier between them, which is proof that the people of Paradise and the people of Hell will not be able to meet each other. However, in the same place, there is mention of them being able to observe each other, the purpose of which seems to be that, upon seeing the inmates of Hell, the dwellers of Paradise may express gratitude for the favours of their Lord, Who kept them on the right path and made them the heirs of the blessings of Paradise, and so that the people of Hell may feel envious of the blessings received by the people of Paradise and therefore sorry for the evil deeds they committed during their worldly lives. This subject has been elucidated in detail in Surah Al-A‘raf, verses 41 to 51.
“However, as far as the meeting of people from different levels of Paradise is concerned, different places and stages of Paradise have been mentioned in the Quran and the Hadith, but there is no mention of any obstacles in the meeting of those who live in these different places and levels of Paradise. On the contrary, Allah the Exalted says in the Holy Quran that ‘those who believe and whose children follow them in faith — with them shall We join their children. And We will not diminish anything from (the reward of) their works.’ (Surah at-Tur, 55:22)
“Likewise, it has been mentioned in a hadith that those whose three young children die, Allah will have mercy on those children and will admit their parents into Paradise along with them. (Sahih Bukhari, Kitab al-jana’iz, Bab fadli mun mata lahu waladun fahtasab)
“Apart from this, it is also worth mentioning that the separation of the permanent residence of the people of different levels in Paradise is another matter, and it is another thing for those of different levels to mix with each other, about which there is no mention of any kind of obstacle in the Quran or the Hadith. Rather, the Holy Quran has stated the following fact about the people of Paradise:
لَهُمۡ فِيۡهَا مَا يَشَآءُوۡنَ
“‘They will have therein what they wish for.’ (Surah an-Nahl, Ch. 16: V. 32)
“It further states:
لَهُمۡ مَّا يَشَآءُوۡنَ عِنۡدَ رَبِّهِمۡ
“‘They will have with their Lord whatever they desire.’ (Surah az-Zumar, Ch. 39: V. 35)
“It also states:
وَ لَكُمۡ فِيۡهَا مَا تَشۡتَهِيۡۤ اَنۡفُسُكُمۡ وَلَكُمۡ فِيۡهَا مَا تَدَّعُوۡنَ
“‘Therein you will have all that your souls will desire, and therein you will have all that you will ask for.’ (Surah Ha Mim as-Sajdah, Ch. 41: V. 33)
“Thus, these verses prove that if the heavenly dwellers of different ranks want to meet any of their loved ones, then their wish shall be fulfilled in Heaven. […]”
