How is the heart affected by the Qur’an and softened?

To be affected by the Quran, a Muslim should be in a state of ritual purity (wudu) and sit with proper etiquette. He should recite his daily portion (wird) with tartil (slow, rhythmic recitation) and tadabbur (contemplation), and with a beautiful voice, while observing the rights of the verses and crying or feigning crying during recitation. He must also venerate its Speaker, Allah Almighty, and be present in heart during the recitation. He should avoid excessive articulation of letters at the expense of understanding and contemplation, and abstain from sins and transgressions, which are a veil between the servant and the word of his Lord.
