Hadith 17:267
Yazid ibn Harun narrated to us, he said: Asim narrated to us, from al-Hasan, that the Messenger of Allah (may Allah bless him and grant him peace) saw some people passing a drawn sword among themselves. He said: "May Allah curse these people." I (the narrator) said: "It was in the mosque." He said: "No, rather it was in one of the courtyards of the mosque."
حدثنا يزيد بن هارون قال حدثنا عاصم عن الحسن أن رسول الله صلى الله عليه وسلم رأى قوما يتعاطون سيفا مشهورا فقال لعن الله هؤلاء فقلت انه كان في المسجد فقال لا بل في رحبة من رحاب المسجد
