Gardens of perpetual residence, whose doors will be opened to them.-Quran Verses

4-Surah An-Nisa ( The Women ) 20

But if you want to replace one wife with another and you have given one of them a great amount [in gifts], do not take [back] from it anything. Would you take it in injustice and manifest sin?

﴿20﴾وَإِنْ أَرَدتُّمُ اسْتِبْدَالَ زَوْجٍ مَّكَانَ زَوْجٍ وَآتَيْتُمْ إِحْدَاهُنَّ قِنطَارًا فَلَا تَأْخُذُوا مِنْهُ شَيْئًا ۚ أَتَأْخُذُونَهُ بُهْتَانًا وَإِثْمًا مُّبِينًا

Quran's Tafhim ( explanation)

*52) The words mufattahat-al-lahum-ul-abwab may have several meanings: (1) They will go about in the Gardens (Paradise) freely without any hesitation; (2) no effort will have to be made to open the gates of Paradise: they will open automatically as soon as they will have the desire to enter them; (3) the angels appointed for keeping Paradise will open the gates for them as soon as they see them. This third meaning has been expressed more clearly at another place in the Qur'an, thus: "When they arrive there, and its gates shall already have been opened, its keepers will say: Peace be upon you: you have fared well: enter here to dwell for ever. " (Az-Zumar: 73)
