It is narrated from Sayyiduna Umar bin Khattab (may Allah be pleased with him), he said: Let not your love make you insane, and let not your enmity incite you to destruction. I asked: How is that? He said: That when you love, you love like a child, madly, considering everything to be for him alone; and when you bear enmity, you wish that the one you hate be destroyed altogether.
