اَللَّهُمَّ (إِنَّهَا) أَمَتُكَ وَبِنْتُ عَبْدِكَ وَبِنْتُ أَمَتِكَ كَانَتْ يَشْهَدُ أَنْ لَا إِلَهَ إِلَّا أَنْتَ وَأَنَّ مُحَمَّدًا عَبْدُكَ وَرَسُوْلُكَ وَأَنْتَ أَعْلَمُ بِهِ اَللَّهُمَّ إِنْ كَانَتْ مُحْسِنَةً فَزِدْ فِي إِحْسَانِهَا وَإِنْ كَانَتْ مُسِيْئَةً فَتَجَاوَزْ عَنْ سَيِّئَاتِهَا اَللَّهُمَّ لَا تَحْرِمْنَا أَجْرَهَا وَلَا تَفْتِنَّا بَعْدَهَا

Alla-humma, (innaha) ‘amatuka, wa bintu 'abdika, wa bintu amatika, kaanat yashhadu an laa ilaaha illaa anta, wa anna mu’hammadan ‘abduka wa rasooluka, wa aanta a’lamu bihi. Alla-humma, in kaanat mu'hsinatan fajid fi ehsaa-niha, wa in kaanat musi-atan fataja-waz ‘an saiyyi-aa-tiha. Alla-humma laa-ta'harimna-ajraha, wala-taftinna ba'adaha.

O Allah, this woman is Your servant, the daughter of Your male servant, the daughter of female servant. She testified that there is no true ilaah but you and that Muhammad (ﷺ) is your servant and your messenger. And you are more aware of it. O Allah, if she is a doer of good, then increase her goodness. And if she has sinned, then forgive her. O Allah, do not deprive us of her reward and do not tempt us after that.
