In a Hadith, the Holy Prophet ﷺ said,

“The person who when he gives something to someone, he gives it for Allah, when he stops from spending something, he stops spending for the sake of Allah, if he loves someone, he loves them for Allah, and if he keeps enmity with someone, he does it for Allah, his Iman is perfect.”

Once a non-Muslim made some insulting comments about the Holy Prophet ﷺ in front of Hadhrat Ali RAA. Hadhrat Ali RAA could not tolerate anyone saying anything derogatory about the Holy Prophet ﷺ. He threw that person on the ground and got on top of him. When that person saw that he was powerless, he spat on Hadhrat Ali’s RAA face. As soon as he did that Hadhrat Ali RAA got up and let go of him. Someone said, “Hadhrat! Now he was being even more insulting. Why did you let him go?” Hadhrat Ali RAA replied, “Initially when I attacked him, it was out of my love for the Holy Prophet ﷺ because he had insulted him which made me angry. When he spat on my face I became even more angry. But if I hit him now it would have been for my own person. That is why I let him go.”
