Hadith
وعن عمر بن الخطاب رضي الله عنه عن النبي صلى الله عليه وسلم قال:"ما منكم من أحد يتوضا فيبلغ-أو فيسبغ الوضوء- ثم قال: أشهد أن لا إله إلا الله وحده لا شريك له، وأشهد أن محمدًا عبده ورسوله، إلا فتحت له أبواب الجنة الثمانية يدخل من أيها شاء" ((رواه مسلم)). وزاد الترمذي: "اللهم اجعلني من التوابين واجعلني من المتطهرين"
'Umar bin Al-Khattab (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, "Whoever of you performs Wudu' carefully and then affirms: 'Ash-hadu an la ilaha illallahu Wahdahu la sharika Lahu, wa ash-hadu anna Muhammadan 'abduhu wa Rasuluhu [I testify that there so no true god except Allah Alone, Who has no partners and that Muhammad ((ﷺ) is His slave and Messenger],' the eight gates of Jannah are opened for him. He may enter through whichever of these gates he desires (to enter)."
