Hisham ibn Abd al-Malik
In Afghanistan, Islam was spread due to Umayyad efforts particularly under the reign of Hisham ibn Abd al-Malik and Umar ibn AbdulAziz. During the reign of Al-Mu'tasim Islam was generally practiced amongst most inhabitants of the region and finally under Ya'qub-i Laith Saffari, Islam was by far, the predominant religion of Kabul along with other major cities of modern-day Afghanistan.
