Muslim

Muhammad ibn Hatim ibn Maymun narrated to me, Abd al-Rahman ibn Mahdi narrated to us, Mu'awiyah ibn Salih narrated to us, from Rabi'ah, meaning ibn Yazid, from Abu Idris al-Khawlani, from Uqbah ibn Amir. And Abu Uthman narrated to me, from Jubayr ibn Nufayr, from Uqbah ibn Amir, who said: We were responsible for herding the camels, and my turn came, so I brought them back in the evening, and I found the Messenger of Allah, peace and blessings be upon him, standing and speaking to the people. I caught from his words: "There is no Muslim who performs ablution and perfects his ablution, then stands and prays two rak'ahs, turning to them with his heart and face, except that Paradise becomes obligatory for him." He said: So I said, "How excellent is this!" Then someone in front of me said, "The one before it is even better." So I looked, and it was Umar. He said: "I saw you just now." He said: "There is none among you who performs ablution and completes it, 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 will be opened for him, and he may enter from whichever of them he wishes."

Uqba bin 'Amir al-Juhani reported: Verily the Messenger of Allah (ﷺ) said and then narrated (the hadith) like one (mentioned above) except (this) that he said: He who performed ablution and said: I testify that there is no god but Allah, the One, there is no associate with Him and I testify that Muhammad is His servant and His Messenger.
