وَ«أُولَاءِ» بِالْمَدِّ وَالْقَصْرِ لِجَمْعِهِمَا.
Translation: «أُولَاءِ», with extended or shortened pronunciation in the source tradition, is used for both masculine and feminine plurals.
Compare هَؤُلَاءِ الطُّلَّابُ and هَؤُلَاءِ الطَّالِبَاتُ. The same demonstrative serves both plural genders.
