Fortress of the Muslim (Hisn al-Muslim)
After the last tashahhud and before salam
اللّهُـمَّ إِنِّـي أَسْأَلُـكَ بِأَنَّـي أَشْـهَدُ أَنَّـكَ أنْـتَ اللهُ لا إِلـهَ إِلاّ أَنْـت الأَحَـدُ الصَّـمَدُ الَّـذي لَـمْ يَلِـدْ وَلَمْ يولَـدْ وَلَمْ يَكـنْ لَهُ كُـفُواً أَحَـد
Allāhumma innī as'aluka bi'annī ash-hadu annaka ant-Allāh lā 'ilāha 'illā ant, Al-Aḥaduṣ-ṣamad alladhī lam yalid wa lam yūlad wa lam yakun lahu kufuwan aḥad. O Allah, I ask You, by the fact that I bear witness that You are Allah. There is none worthy of worship but You, the Only God, Independent of creation, Who was not begotten and begets not, and none is equal to Him.
