What does one recite in prayer who does not master al-Fatihah and the short surahs?

Question:
May Allah reward you, Your Eminence, father. The questioner says: What is obligatory for the one who does not master the recitation of al-Fatihah and the short surahs in his prayer?

Answer:
The one who does not master the recitation of al-Fatihah recites according to his ability. He recites according to his ability, as long as he is able to recite, even if he does not master it. However, it is obligatory for him to learn. If he refrains from that, he must hasten to learn, and he must not remain in his ignorance and lack of mastery. Otherwise, if he is unable to learn, he prays according to his ability and does not leave the prayer, even if he does not know anything of the Qur'an. He prays and replaces this with dhikr, tasbih, and tahlil, as the Prophet (peace and blessings be upon him) said: . The prayer is not left; pray in any condition.
