It would be relevant to note here that the real wrath fell on lower class such as slaves. They were humiliated, tortured, and sometimes killed. Nevertheless, they were socially weak but not in their character or faith.
For the Quraish members who turned to Islam, the Makkans asked clans’ leaders to upbraid their members. Take for instance, Hazrat Usman was beaten by his uncle Zubair ibn al-Awwam.
When this severe persecution couldn’t dissuade the Prophet and his followers, the leaders sent Utba bin Rabia with worldly offers such as wealth, a beautiful woman or even leadership of Makkah. The Holy Prophet (P.B.U.H) rejected the offer outright.
They even asked Abu Talib to convince his nephew. He tried too, but our Prophet remained undeterred.
