The Holy Prophet (Peace be upon him, his family and his companions) states and it is recorded in Mishkaat Shareef:
Allaah (Almighty and Glorious is He) elevated the status of his servant, who had already attained salvation, in paradise…
I ask the gathering, knowing that the ulamaa know the answer, to tell me how many levels of status are there in paradise? There are a hundred levels of status in paradise and eight doors to enter paradise. There are eight depths of hell. This is mentioned in the Authentic Collection of Hadees in Bukhaari. Allaah Kareem will give each one a level according to his status. So continuing the hadees I was quoting:
Allaah (Almighty and Glorious is He) elevated the status of his servant, who had already attained salvation, in paradise. So that servant asked Allaah [Ta’aalaa]:
O My Sustain-er! On what account have I acquired a higher status, for You had already rewarded me for my deeds?
Almighty Allaah replies:
O My servant! A son of yours is always making dua of salvation for you, and it is due to his dua and seeking forgiveness (istighfaar) for you that we have elevated your status.
