We have been told by the Creator of Heaven of the qualities of those who will go to Heaven. We read in Verse 40 of Surat al-Mumin, or the Believer: "...and he that works a righteous deed – Whether man or woman – And is a believer – Such will enter the garden (of bliss): therein will they have abundance without measure".
We also read in Verses 13 and 14 of Surat al-Ahqaf: (Verily those who say, "Our Lord is Allah", and remain firm (on that path), - On them shall be no fear, nor shall they grieve (13) Such shall be companions of the garden, dwelling therein (for aye): a recompense for their (good) deeds. (14)).
And in Verse 60 of Surat Maryam, or Mary: ("Except those who repent and believe, and work righteousness: for those will enter the garden and will not be wronged in the least. (60) )
All those who submit to Allah, do what He asked and avoid what He proscribed will go to Heaven.
