As a Khalifa is God’s vicegerent on Earth, his person becomes the reflection of Divine attributes, and his actions serve as the true demonstration of Islamic teachings.
Godly people i.e. those who develop a relationship of love with God experience no urge to pursue earthly desires or worldly pleasures. Instead, God remains the sole purpose of their lives.
Khilafat is the heavenly means of sustaining the unity of Islam. It is the Divine institution that fosters the spiritual strength of Muslims.
