Muhabbat e Ilahi Islamic Urdu Book Authorized By Maulana Peer Zulfiqar Ahmad Naqshbandi is an excellent Islamic book on Sufism and love with Allah Ta’ala.

When love of Allah takes possession of the innermost being of Allah’s bondsman, it empties him of every preoccupation except remembrance of Allah. The lover is the most inwardly sincere of all people for Allah.
