Another accepted interpretation of the same words is "Indeed, arising at night is more difficult...," meaning that it will only be done by sincere believers and not others.

[1781] i.e., for recitation of the Qur’ān and for hearing and understanding it.

Assuredly rising in the night, to wake up after [having been in] sleep, is firmer in tread, [more] conducive to [establishing] harmony between the hearing and the heart for the purpose of comprehending Al-Qur'an, and more upright in respect to speech, clearer for utterance [of devotions].
