(Zumar) 39 : 73
وَسِيقَ الَّذِينَ اتَّقَوْا رَبَّهُمْ إِلَى الْجَنَّةِ زُمَرًا ۖ حَتَّىٰ إِذَا جَاءُوهَا وَفُتِحَتْ أَبْوَابُهَا وَقَالَ لَهُمْ خَزَنَتُهَا سَلَامٌ عَلَيْكُمْ طِبْتُمْ فَادْخُلُوهَا خَالِدِينَ
And those who heed their Lord will be led to Paradise in crowds until they reach there, and its door will be opened and its guards will tell them: Peace is upon You; you have done well! Then you enter it forever.
For the forerunners who will enter Paradise without Trial, as told in verses 35: 32, the gates of Paradise are kept open, as told in verses 38: 49-50. ‘Those who heed their Lord’ mentioned in the verse are the believers who will enter Paradise after the Trial. They are mentioned in verse 35: 32 as the moderate. When they reach Paradise, the Messenger has to open the gates of Paradise. See explanation 3: 101-102; 9: 71-72; 37: 50-61; 39: 33-34.
