Muslims continued to migrate secretly until it was 'Umar's turn. He went to the Ka'bah along with his brother Zayed. He prayed openly then he made an announcement of his migration. In his announcement, he threatened anyone who would attempt to pursue him and his brother. In fact, his announcement scared even the most powerful men of Quraish, none had the courage to pursue him.
