Reciting Tayyibah in Kalima, the dua for bringing faith
Laailaha illallahu muhammadur rasoolullah.
There is no one worthy of worship except Allah. Muhammad is the messenger of Allah.
Virtue
On the authority of Hazrat Mu'adh Ibn Jabal (Radi), he said, The Messenger of Allah (ﷺ) said, "Whoever testifies with sincerity that there is no god but Allah and that Muhammad (ﷺ) is the Messenger of Allah, Allah will make Hell forbidden for him."
Reference: Sahih Bukhari, Hadith No: 128
It should be noted that dua'ati is also recited for talkin (reciting) to a forgetful person.
