All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
The matter is different in regard to the being together that is mentioned in verse 69 of Surah al-Nisa [Quran 4] in which Allah Says (what means): {And whoever obeys Allah and the Messenger - those will be with the ones upon whom Allah has bestowed favor of the prophets, the steadfast affirmers of truth, the martyrs and the righteous. And excellent are those as companions.} [Quran 4:69]; it does not require that they are equal to them in the same status/degree.
Al-Qurtubi said in his Tafseer about the interpretation of this verse: "What is meant is that they will be with them in one abode of bliss, enjoying seeing them and being present with them; not that they will be equal with them in degree, for they will vary in degree, and everyone in it will be granted contentment with his lot and would not feel that anyone is favored over him.” [End of quote]
As regards verse 21 from Surah At-Toor [Quran 52], in which Allah Says (what means): {And those who believed and whose descendants followed them in faith - We will join with them their descendants, and We will not deprive them of anything of their deeds. Every person, for what he earned, is retained.} [Quran 52:21], it means that Allah will gather the members of the same family in the same status in Paradise, so that each one of them will be comforted by the other, as a Favor and Grace from Allah.
