Is it permissible to read the Quran in regular clothes, meaning not in prayer garments?

There is no harm in reciting the Quran without wearing prayer attire for either males or females, as the conditions for reciting the Quran are not the same as those for prayer. There is no religious text specifying a particular dress code for the reciter. However, it is preferable for the reciter to be in a good state in terms of their clothing and sitting posture, out of reverence for the word of Allah and for deeper contemplation of it.
