Is it recommended to chant the Quran when reviewing it to ensure humility and benefit, or is there no harm in reading it like other texts, with less humility, and sufficing with frequent review?

The reward for reciting the Quran with tartil (slow, rhythmic recitation) and contemplation is greater, as Allah says: "Do they not then contemplate the Quran?" (47:24) and "A Book We have sent down to you, full of blessings, that they may ponder over its verses" (38:29). Contemplation (tadabbur) is reflecting on the meanings of the Quran, its principles, and its outcomes. It is the key to knowledge and understanding, increases faith, and teaches about Allah, His attributes, and the path leading to Him.

Nevertheless, quick recitation is permissible for revision and memorization, provided it does not compromise correct recitation. In such cases, a general understanding of the meanings can still be achieved. Some Companions and early Muslims (Tabi'in) recited the entire Quran in a single rak'ah. Imam Al-Shafi'i is reported to have completed sixty recitations of the Quran during Ramadan. Ibn 'Uthaymeen clarified that the prohibited speed is that which causes the omission of some letters or vowel marks. However, speed that maintains the words, letters, and grammatical inflections is permissible.
