Translation:

73. And those who feared their Lord will be led to the Garden in crowds: until behold they arrive there; its gates will be opened: and its Keepers will say: "Peace be upon you! Well have ye done! Enter ye here to dwell therein."

4351. The righteous ones will also go in crowds, and not be alone. There is now a true sorting out. Verses 73-75 are parallel in contrast to verses 71-72 above.

4352. The angels in heaven are not surprised at the advent of the good and righteous souls. They are glad; they greet them with the salutation of Peace; they congratulate them; and they welcome them in.
