Musannaf Ibn Abi Shaybah

Hazrat Zir, may Allah have mercy on him, says that when the righteous were mentioned in the presence of Hazrat Abdullah bin Mas'ud, may Allah be pleased with him, he would immediately proclaim the name of Hazrat Umar, may Allah be pleased with him. And he would say! Indeed, his acceptance of Islam was a help to the Muslims and his caliphate was a victory for the Muslims. By Allah! I do not know of anything on earth except that everything felt the absence of Hazrat Umar, may Allah be pleased with him, even the thorny trees. By Allah! Indeed, I used to think that there was an angel between his two eyes who guided him to the straight path and directed him. And by Allah! Indeed, Satan was afraid that he might cause any mischief in Islam because Hazrat Umar, may Allah be pleased with him, would turn him back from it. By Allah! If I were to know that even a dog loves Hazrat Umar, may Allah be pleased with him, I would also begin to love that dog.
