There is no Harm in Preferring to Recite One Chapter of the Qur'an Over Others

Question :

What is the ruling on preferring to recite one chapter of the Qur'an more than others? I ask this because I love to read chapter "Maryam," because I find special peace and comfort when I read it.

Answer:

Even though the entire Qur'an is Allah's Speech, there is no harm in preferring to recite certain chapters of the Qur'an over others, and for any reason.

There is no way to give part of the Qur'an real preference over the other since it is the Word of Allah, but from the view of the beautiful and magnificent meanings that are mentioned in it, then some of it can be given preference. This is confirmed by the saying of the Prophet ﷺ :
"Indeed, the greatest Surah in Allah's Book is Surat Al-Fatihah, and the greatest Verse in Allah's Book is Ayat Al-Kursi."

When the Prophet ﷺ sent a group of Companions on a mission, their leader would always finish his recitation of the Qur'an by reading Surat Al-Ikhlas. The Prophet ﷺ later said :
"Ask him why he did that."

When asked, the man said, "Because it describes the Most-Beneficent, and I love to read it."

When the Prophet ﷺ heard of the man's answer he said :
Tell him that indeed, Allah loves him."

It is also confirmed that the Prophet ﷺ said:
"Indeed, Surat Al-Ikhlas is equivalent to one-third of the Qur'an."

Since the questioner mentioned a love for reciting Surah Maryam; with its beautiful and meaningful stories, mention of the rewards in the Hereafter, a warning to those who deny and disbelieve in Allah's signs, and the great wealth that Allah has given and other than that which is mentioned in it, then there is no harm in that.
