أَعُوْذُ بِاللَّهِ مِنَ الشَّيْطَانِ الرَّجِيمِ
اَعُوْذُ بِاللّٰهِ مِنَ الشَّيْطَانِ الرَّجِيْمِ
A'oodhu billaahi minash-Shaytaanir-rajeem
I seek refuge in Allah from Satan the outcast.
Allah's Messenger (ﷺ) said, "Satan comes to one of you and says, 'Who created so-and-so? 'till he says, 'Who has created your Lord?' So, when he inspires such a question, When he reaches that stage, he should say - (The dua is mentioned above)

آمَنْتُ بِاللَّهِ وَرُسُلِهِ
اٰمَنْتُ بِاللّٰهِ وَرُسُلِهٖ
Aamantu billaahi wa Rusulihi
I believe in Allah and His Messenger.
It is narrated on the authority of Abu Huraira (RA) that the Messenger of Allah (ﷺ) said: Men will continue to question one another till this is propounded: Allah created all things but who created Allah? He who found himself confronted with such a situation should say: (The dua is Mentioned above)
371. If afflicted with doubt in one's faith #3
اَللَّهُ أَحَدٌ، اللَّهُ الصَّمَدُ، لَمْ يَلِدْ وَلَمْ يُولَدْ، وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ
اَللّٰهُ اَحَدٌ اَللّٰهُ الصَّمَدُ لَمْ یَلِدْ وَلَمْ یُوْلَدْ وَلَمْ یَكُنْ لَّهٗ كُفُوًا اَحَدٌ
Allahu 'Ahad. Allahus-Samad. Lam yalid wa lam yoolad. Wa lam yakun lahu kufuwan 'ahad
He is Allah, [who is] One, Allah, the Eternal Refuge. He neither begets nor is born, Nor is there to Him any equivalent.
Abu Hurairah (RA) reported that Messenger of Allah (ﷺ) said: People will continue to ask one another(questions) till this is pronounced: Allah created all things, but who created Allah ? Whoever comes across anything of that, he should say: (The dua is mentioned above) Then he spit three times on his left side, seeking refuge with Allah from Satan.
