Paradise and hell word count in the Qur'an

Paradise - الجنة (al-jannah)

The word paradise (الجنة, al-jannah, literally means "the garden". This word appears only in the singular form and it is a feminine word - it ends on ta marbuta (ة). When a word is not in a context of an Arabic text, the ta marbuta at the end is not pronounced, so it is read as jannah, not jannat. But when reading the Qur'an in Arabic, the ta marbuta would be read as "t". There are 3 forms of الجنة:

• ٱلْجَنَّةُ (al-jannatu) - nominative
• ٱلْجَنَّةِ (al-jannati) - genitive
• ٱلْجَنَّةَ (al-jannata) - accusative

And sometimes this word actually refers to the jinns and not paradise:

• ٱلْجِنَّةِ (al-jinnati)

This word sometimes appears with some prefixes.

Hell - جهنم (jahannam)

List of occurrences of the word "hell" (جهنم, jahannam). All occurrences are in the singular. This word sometimes occurs with some prefix. The forms without prefix appear in two forms:

• جَهَنَّمُ (jahannamu) - nominative
• جَهَنَّمَ (jahannama) - genitive

Unlike most Arabic words, the word jahannam has 4 (not 3) root letters (ج-ه-ن-م, j-h-n-m).
