Is dedicating a time to read the Quran after Asr prayer considered a Bid'ah (innovation)?

Reciting the Quran is a great act of worship, for each letter earns ten good deeds, as reported from the Prophet, peace and blessings be upon him. Therefore, always be keen on reciting it. However, do not designate a specific time for recitation, such as after Asr prayer, without a reason, so that you do not fall into the sin of an additional innovation (bid'ah idafiyyah). The principle concerning acts of worship is that they are prescriptive (tawqif), unless that time happens to be your free time without believing in its superiority.
