He made the Iqta System hereditary.
He extended the principle of heredity to the army. The soldiers were not paid by cash but by assignments on land revenue of villages (Vajeha). This technique led to many abuses.

He encouraged the practice of slavery and selected young boys from the conquered territory for the purpose. Diwan-i-Bandagan was created as the department for slaves.
