Khalid Ibn Walid (رضي الله عنه) on his deathbed
Abu Sulayman, Khalid bin Al-Walid (رضي الله عنه), the commander of the Muslim armies, the veteran among Muslim soldiers, the protector of Islam and the Sword of Allah that was raised above His enemies, said while dying,
“I have participated in so-and-so number of battles. There is not a part of my body, but suffered a shot (of an arrow), a stab (of a spear) or a strike (of a sword). Yet, here I am, I die on my bed just as the camel dies! May the eyes of the cowards never taste sleep.”
He, may Allah be pleased with him, was sorry and in pain because he did not die as martyr in battle. He was sad that he had to die on his bed!
