I could not find the reference to the hadith bro, but I did find a few of these wordings on a sect site (more like a story):

At this moment, a voice from within the tent announced a newcomer.

"Amir ul-Muminin!" said the visitor’s wife. "Congratulate your friend. God has blessed him with a son."

The Bedouin was taken aback at the words, Amir ul-Muminin. His visitor was the caliph, himself. He was overtaken by fear.

"I beg your pardon, Amir ul-Muminin," he said, with fear on his face. "I have been rude to you."

"Don’t worry about that, friend," Umar reassured him. "You are just as much a human being as I am. In the sight of God, there is neither high nor low. We are all equal. God loves those who love His creatures. I have only done my duty, for, in Islam, the leader of a people means the servant of the people."
