It was narrated that Ka'b bin 'Ujrah said that: He entered the masjid and 'Abdur-Rahman bin Umm Al-Hakam was delivering the Khutbah while seated. "He said: 'Look at this man who is delivering the khutbah while seated when Allah (SWT) says: And when they see some merchandise or some amusement they disperse headlong to it, and leave you standing.'"
