The sound feminine plural (جَمْع الْمُؤَنَّث السَّالِم) is raised with a ḍamma — but takes a kasra in nasab as well as in jarr.
Definition and i'rab
هُوَ مَا دَلَّ عَلَى أَكْثَرَ مِنِ اثْنَتَيْنِ بِزِيَادَةِ أَلِفٍ وَتَاءٍ فِي آخِرِهِ. وَإِعْرَابُهُ: يُرْفَعُ بِالضَّمَّةِ، وَيُنْصَبُ وَيُجَرُّ بِالْكَسْرَةِ.
“It is what indicates more than two feminine by adding an alif and ta' at its end. Its i'rab: raised with the damma, and put into nasab and jarr with the kasra.”

Understand it

Drop the ة and add ـَات: مُسْلِمَةٌ becomes مُسْلِمَاتٌ.

The nasab is the surprise: a kasra where every other ism takes a fatḥa.

The special cases

Seven categories that express i'rab their own way — by letters instead of vowels, or by not showing it at all.

The nasab is the surprise. Every other ism you have met takes a fatḥa in nasab; this one takes a kasra. رَأَيْتُ الْمُسْلِمَاتِ, I saw the Muslim women — a direct object, in nasab, wearing a kasra.

It is the mirror of the partly declining ism, which borrows a fatḥa for its jarr. Here a kasra is borrowed for the nasab.

How to spot it
Recognition test
An ending in ـَات. Ḍamma means rafa; kasra means nasab or jarr — never assume the kasra is jarr.
The kasra is not proof of jarr

A kasra on a ـَات word is not proof of jarr.

رَأَيْتُ الْمُؤْمِنَاتِ — the object of a verb, so it is manṣūb, and yet it ends in a kasra.

This is the clearest single proof that the ending is not the i'rab. Category first, always: once you know the word is a sound feminine plural, the kasra tells you it is nasab *or* jarr, and only the role decides which.
