(2) باب مِنْ فَضَائِلِ عُمَرَ رضى الله تعالى عنه
Abu Huraira reported that Umar b. Khattab came to Allah's Messenger (ﷺ) while there were some women with him and they were raising their voices above the voice of Allah's Messenger (ﷺ) and when Umar sought permission to get into the house they went behind the curtain hurriedly. The rest of the hadith is the same.
