What is Faith?

Do not become unbalanced by love or hate Umar once cautioned: “Do not become mad with love for anyone, nor seek to destroy with your dislike.” Aslam asked Umar that what this meant. “It means that when you love anyone, there is the danger of falling head over heels, like a child, and when you dislike someone, you become bent upon destroying him.” (AL-ADAB AL-MUFRAD)
