Hadith 29:125
Waki’ narrated to us, he said: Mubarak narrated to us, from al-Hasan, he said: Umar said when the statement of Khalid ibn al-Walid reached him: "I shall certainly remove Khalid, and I shall certainly remove al-Muthanna, until they know that Allah grants victory to His religion, not to them."
حدثنا وكيع قال حدثنا مبارك عن الحسن قال قال عمر لما بلغه قول خالد بن الوليد لأنزعن خالدا ولأنزعن المثنى حتى يعلما أن الله ينصر دينه ليس إياهما
