Praise be to Allah.
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.
