During Yarmouk battle, the Roman general, Mahan addressed Khalid bin Waleed(رضي الله عنه) and said:

“It looks as if poverty, nakedness and starvation has compelled you to come here. If you wish I am willing to give each of you ten dinars, expensive clothing and good food. You can take these things and leave. Next year too I can send you these things; you do not have to take the trouble to come here?”

Khalid bin Waleed (رضي الله عنه) was enraged on hearing these scornful and arrogant words, and answered:

“Mahan, listen to me very carefully! You are mistaken about the reason why we are here. We are people who drink the blood of our opponents. We have heard that Roman blood is very delicious, and we have come here to enjoy it?”
