What is the ruling if the reciter is unable to complete the recitation of the Qur'an audibly, melodiously, and with proper tajweed due to shortness of breath, hoarseness, and tongue-tiedness?

Reading the Qur’an aloud is not obligatory, and reading it silently is better in some circumstances. It is advisable to continue reading the Qur’an without overexerting oneself; merely moving the tongue and hearing oneself is sufficient. Care must be taken to learn the rules of Tajwid, and there is no harm in seeking treatment with permissible medications and consulting a doctor for hoarseness and shortness of breath.
