Is it sufficient for an unlettered woman who has memorized only Surat Al-Fatiha and Surat Al-Ikhlas to repeat them in every rak'ah of prayer?

Reciting only Surah Al-Fatihah is sufficient in prayer because it is the Mother of the Qur’an and a pillar of the prayer. If it is easy to recite Surah Al-Ikhlas along with it, this is better, as it is equivalent to one-third of the Qur’an. It is recommended to recite Surah Al-Ikhlas frequently outside of prayer due to its immense reward. If it is easy to learn other short surahs, such as Al-Mu'awwidhatayn and surahs like "Tabbat," "An-Nasr," "Al-Kafirun," and "Al-Kawthar" from relatives, this is a great good.
