طَلْحَةُ is used as a male personal name but ends with a feminine tāʾ. Proper-name status and feminine tāʾ can therefore combine.
سَلَّمْتُ عَلَى طَلْحَةَ — I greeted Ṭalḥah.
عَلَى: preposition; طَلْحَةَ: genitive in function after ʿalā, marked with fatḥa because it is a diptote.
The relevant feminine marker is part of the word’s form; it does not depend on the bearer being female.
