Umar bin khattab stammered man who became the friend of the Prophet Muhammad most powerful, his body very hard, he became a stick at that time.
his body like a flame-lined steel armor, as it were
like the sun shining on the earth, so for example he spent time with other companions in bela rasullah, the greatest blessings is when rasullah born on earth, all pit to him, hopefully who read this gets hidayah and syafa'at prophet.
