Paradise, garden
Surah (2:35)
وَقُلْنَا يَـٰٓـَٔادَمُ ٱسْكُنْ أَنتَ وَزَوْجُكَ ٱلْجَنَّةَ وَكُلَا مِنْهَا رَغَدًا حَيْثُ شِئْتُمَا وَلَا تَقْرَبَا هَـٰذِهِ ٱلشَّجَرَةَ فَتَكُونَا مِنَ ٱلظَّـٰلِمِينَ« And We said, "O Adam, dwell, you and your wife, in Paradise and eat therefrom in [ease and] abundance from wherever you will. But do not approach this tree, lest you be among the wrongdoers." »
Surah (55:46)
وَلِمَنْ خَافَ مَقَامَ رَبِّهِۦ جَنَّتَانِ« But for he who has feared the position of his Lord1 are two gardens - »
Surah (3:133)
۞ وَسَارِعُوٓا۟ إِلَىٰ مَغْفِرَةٍ مِّن رَّبِّكُمْ وَجَنَّةٍ عَرْضُهَا ٱلسَّمَـٰوَٰتُ وَٱلْأَرْضُ أُعِدَّتْ لِلْمُتَّقِينَ« And hasten to forgiveness from your Lord and a garden [i.e., Paradise] as wide as the heavens and earth, prepared for the righteous »
The Paradise promised to believers. The root ج-ن-ن means 'to hide, to cover', as Paradise is a garden covered with vegetation.
