Who was the king during Saint Kabir's life-time?

Once, there was discussion about God. Sikh Guru, gobind Singh ji asked, "Brothers! Who was the king during Kabir's life-time?"

Then, some old persons said, "Humanyoo". Someone said, "Pithora". One said, "Sikandar". One said, "Madan Paal was the king". There was a big debate for a long time. ‪#‎Gurugobindsingh‬ Ji continued to listen. “We cannot reach them; the God's men are high. The castes, 'varnas' and kingdoms, all remain lower.” They all became silent. People sitting there asked, "O Guru Ji ! Why did you ask? Please share the reason.

Guru Gobind Singh Ji said, "This is the glory of 'Naam'. Kabir was a poor weaver. Everyone knows him. And the king was the owner of large kingdoms of the world, but still no one knows him (now). See the glory of the 'Name'. There were thousands of Pandits, Shah, astrologers, kings, but all are unknown (now). By the grace of 'Name', Kabir is called the knowledgeable and 'Sidh' (perfect). O Sikhs! The 'Name' is great. It was 'Sikandar Shah' (who was the king during the lifetime of saint Kabeer das). He conquered India, he bowed before Kabir Ji after seeing the miracle of Kabir. O People ! He, who repeats the 'Name', is the Sikh of the Guru. Repeat the 'Name' and do the 'seva' (service) with thy hands."
