Maryam - 19:61

جَنَّاتِ عَدْنٍ الَّتِي وَعَدَ الرَّحْمَنُ عِبَادَهُ بِالْغَيْبِ إِنَّهُ كَانَ وَعْدُهُ مَأْتِيًّا
[19:61]
The gardens of perpetuity which the Beneficent Allah has promised to His servants while unseen; surely His promise shall come to pass.
Gardens of Eternity, those which (Allah) Most Gracious has promised to His servants in the Unseen: for His promise must (necessarily) come to pass.
Gardens of Eden, which the Beneficent hath promised to His slaves in the unseen. Lo! His promise is ever sure of fulfilment -
