Yes, we found true the promise

When the people of Paradise will enter Paradise they will find the promise of their Lord to be true. They will see the rewards which He promised them. They will see the rivers of wine and milk. They will delight on the immense beauty of their virgins. There will be no foul language in Paradise. It will be peace. There will be no fear of anything. 

Best of all they will have the Pleasure of their Lord and will get to see Him.

They will then call out to the inhabitants of the Fire. They will tell them that they have found the promise of Allaah to be true. Allaah promised them a reward for obeying Him and believing in Him and His Messengers. He sent them this message and promise by means of His Messengers. 

They will ask the inhabitants of the Fire if they found the promise to be true as well. Allaah promised a humiliating torment to those who disbelieved in Allaah and His Messengers. Those who disobeyed Allaah would face a painful torment. 

The inhabitants of the Fire will respond by saying yes. 

The curse of Allaah is upon the wrongdoers.

And the companions of Paradise will call out to the companions of the Fire, "We have already found what our Lord promised us to be true. Have you found what your Lord promised to be true?" They will say, "Yes." Then an announcer will announce among them, "The curse of Allah shall be upon the wrongdoers."

[Qur'aan 7:44]
