The Quran

وَسيقَ الَّذينَ اتَّقَوا رَبَّهُم إِلَى الجَنَّةِ زُمَرًا ۖ حَتّىٰ إِذا جاءوها وَفُتِحَت أَبوابُها وَقالَ لَهُم خَزَنَتُها سَلامٌ عَلَيكُم طِبتُم فَادخُلوها خالِدينَ

Muhammad Asad

But those who were conscious of their Sustainer will be urged on in throngs towards paradise till, when they reach it, they shall find its gates wideopen;¹ and its keepers will say unto them, "Peace be upon you! Well have you done: enter, then, this [paradise], herein to abide!"

Lit., "and its gates have [or "will have"] been opened", i.e., before their arrival, as indicated by the particle wa (lit., "and"), which in this case denotes precedence in time (Zamakhshari). Cf. in this connection 38:50 - "gardens of perpetual bliss, with gates wide-open to them".
