The Messenger of Allah ﷺ led nineteen military expeditions, fighting in eight of them. Abu Bakr did not say "of them" in his version, and he said in his narration, "Abdullah bin Burayda told me."
و حدثنا أبو بكر بن أبي شيبة حدثنا زيد بن الحباب ح و حدثنا سعيد بن محمد الجرمي حدثنا أبو تميلة قالا جميعا حدثنا حسين بن واقد
غزا رسول الله ﷺ تسع عشرة غزوة قاتل في ثمان منهن ولم يقل أبو بكر منهن وقال في حديثه حدثني عبد الله بن بريدة
