It is narrated from Sayyiduna Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever performs ablution and performs it well, then raises his gaze towards the sky and recites this supplication: "I bear witness that there is no god but Allah, He is alone, He has no partner, and I bear witness that Muhammad is His servant and Messenger," then all eight gates of Paradise will be opened for him, and he may enter through whichever one he wishes.
It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever performs ablution and performs it well, then recites this supplication: "Ashhadu an la ilaha illallah wahdahu la sharika lahu, wa anna Muhammadan abduhu wa rasuluhu" (I bear witness that there is no god but Allah, He is alone, He has no partner, and that Muhammad is His servant and Messenger), then three doors from the doors of Paradise will be opened for him, and he may enter through whichever of them he wishes.
