The Reward of Allah Azawajal

Bilal was tortured by the people of Mecca and by Umayy ibn Khaled from particular, but he never even gave them one word to please them. And look at how Allah Subh'anaHu Wa Ta-A'laa rewarded him for we as Muslims firmly believe that there is an expression in Arabic: Al-Jazah U-min-Jin-Sillamal. The reward or the punishment will be the exact same as what you were doing to get that reward or that punishment.
