Musannaf Ibn Abi Shayba 23:126

Muhammad ibn Bishr narrated to us, he said: Zakariyya narrated to us, he said: al-Hawwari narrated to us, that Abdullah ibn Umar said: "Indeed, the handholds of the religion and its foundation are the prayer and the zakat; one does not separate between them, and the pilgrimage to the House, and the fasting of Ramadan. And indeed, among the righteous deeds are charity and jihad." Then he stood up and departed.
