Uqba bin Amir reported,

We were responsible for tending the camels, and when my turn came, I brought them back in the evening. I found the Messenger of Allah ﷺ standing and addressing the people. I caught these words from him, "There is no Muslim who performs ablution well, then stands and prays two units of prayer, turning toward them with his heart and face, except that Paradise becomes guaranteed for him."I said, "How excellent this is!"Then a speaker in front of me said, "The one before it was even more excellent."I looked, and there was Umar. He said, "I saw you arrive just now."He continued, "There is none among you who performs ablution and completes it thoroughly, then says, 'I bear witness that there is no god but Allah and that Muhammad is the servant of Allah and His Messenger,' except that the eight gates of Paradise are opened for him, and he may enter through whichever of them he wishes."

Sahih

عن عقبة بن عامر قال

كانت علينا رعاية الإبل، فجاءت نوبتي، فروحتها بعشي، فأدركت رسول الله ﷺ قائما يحدث الناس، فأدركت من قوله: ما من مسلم يتوضأ فيحسن وضوءه، ثم يقوم، فيصلي ركعتين مقبل عليهما بقلبه ووجهه إلا وجبت له الجنة. قال: فقلت: ما أجود هذه! فإذا قائل بين يدي يقول: التي قبلها أجود، فنظرت، فإذا عمر! قال: إني قد رأيتك جئت آنفا. قال: ما منكم من أحد يتوضأ، فيبلغ (أو فيسبغ) الوضوء، ثم يقول: أشهد أن لا إله إلا الله وأن محمدا عبد الله ورسوله إلا فتحت له أبواب الجنة الثمانية، يدخل من أيها شاء.

His saying, "{And those who feared their Lord will be driven to Paradise in groups until, when they reach it while its gates have been opened and its keepers say to them, 'Peace be upon you; you have become pure, so enter it to abide eternally'}." His saying, "while its gates have been opened" means that Paradise has gates that open and close, and they have names, and it has come in the hadith that their number is eight
