Hadith: The Prophet (may Allah's peace and blessings be upon him) was on a journey and he performed the ‘Ishā prayer, reciting in one of the two Rak‘ahs Sūrat At-Tīn. I have never heard anyone with a better voice or recitation than his

عن الْبَرَاء بْن عَازِبٍ رضي الله عنهما «أن النبي صلى الله عليه وسلم كان في سفر، فصلى العشاء الآخِرَةَ، فقرأ في إحدى الركعتين بِالتِّينِ وَالزَّيْتُون فما سمعت أحدًا أحسن صوتًا أو قراءة منه».
[صحيح] - [متفق عليه]

Al-Barā ibn ‘Āzib (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) was on a journey and he performed the ‘Ishā prayer, reciting in one of the two Rak‘ahs Sūrat At-Tīn. I have never heard anyone with a better voice or recitation than his.
Sahih/Authentic. - [Al-Bukhari and Muslim]

Explanation

The Prophet (may Allah's peace and blessings be upon him) recited Sūrat At-Tīn, which is a short Sūrah, in the first Rak‘ah of the ‘Ishā prayer, because he was on a journey. While traveling, one should be keen on making things easier because of the hardship of traveling. Even though the Prophet (may Allah's peace and blessings be upon him) was on a journey, he didn't abandon what evokes humility and attentiveness of the heart in prayer when listening to the Qur'an, which is beautifying one's voice with the recitation of the Qur'an in prayer.
