It was narrated that ‘Umar bin Al-Khattab said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘Whoever performs Wudu' and does it well, then says: “Ashhadu an lailaha ill-Allah wa ashhadu anna Muhammadan ‘abduhu wa rasaluh (I bear witness that there is none worthy of worship except Allah, and I bear witness that Muhammad is His slave and Messenger),” eight gates of Paradise will be opened for him, and he may enter through whichever one he wishes.” (Sahih)
