Who was al-Miqdad?
Al-Miqdad belonged to Kunda's tribe. He escaped from his tribe and inhabited Makkah.
There he belonged to a man called al-Aswad bin Abid Yaqut al-Zuhry. So, people called him al-Miqdad bin al-Aswad. In connection with al-Miqdad, this verse came down from the sky:
Call them with their fathers' names
For this reason, people called him al-Miqdad bin al-Aswad.
Islam rose from the top of the Hiraa Mount.
Al-Miqdad became twenty-four years old. He heard about our Master Muhammad's mission. He hurried to believe in the new religion.
He kept his Islam a secret. He met our Master Muhammad [s] secretly. Thus, he was among the earlier Muslims. He always felt the Muslims' sufferings.
