Invocations after the final Tash-ahhud and before ending the prayer

((اللَّهُمَّ إِنِّي أَسْأَلُكَ بِأَنَّي أَشْهَدُ أَنَّكَ أَنْتَ اللَّهُ لاَ إِلَهَ إِلاَّ أَنْتَ الْأَحَدُ الصَّمَدُ الَّذِي لَمْ يَلِدْ وَلَمْ يُولَدْ وَلَمْ يَكُنْ لَهُ كُفُواً أَحَدٌ))

Allāhumma innī asʾaluka bi-annay ashhadu annaka anta llāhu lā ilāha illā anta l-ʾaḥadu aṣ-ṣamadu alladhī lam yalid walam yūlad walam yakun lahu kufūan aḥad

O Allah, I ask You, as I bear witness that You are Allah, none has the right to be worshipped except You, The One, AS-Samad Who begets not nor was He begotten and there is none like unto Him.
