Eight Doors of Jannah Open

‘Umar bin Khattaab (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “Whoever performs a perfect wudhu and thereafter recites the following du‘aa, eight doors of Jannah will open for him, and he may enter from whichever door he wishes:

أَشْهَدُ أَنْ لَّا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيْكَ لَهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُوْلُهُ اَللَّهُمَّ اجْعَلْنِيْ مِنَ التَّوَابِيْنَ وَاجْعَلْنِيْ مِنَ الْمُتَطَهِّرِيْنَ

I testify that there is no deity besides Allah, who is alone, without any partner, and I testify that Muhammad (sallallahu ‘alaihi wasallam) is His servant and messenger. O Allah! Make me from among those who constantly repent, and make me from among those who are pure! (Sunan Tirmizi #55)
