Jabir said, "While the Messenger of Allah, may Allah bless him and grant him peace, was delivering an address, his eyes would become red, he would raise his voice and he would become very angry until he was like someone admonishing an army.
He would say, "(Guard youselves against attack) in the morning and the evening.' He would say, 'I have been sent at a time when I and the Last Hour are like these two,' and he joined together his index finger and middle finger.' He would say, 'Following on from that: the best speech is the Book of Allah. The best guidance is the guidance of Muhammad, may Allah bless him and grant him peace.
The worst of matters are the new ones, and every innovation is misguidance.' Then he would say, 'I am more entitled to every believer than his own self. Whoever leaves property, it is for his family. Whoever leaves a debt or family, it is for me and on me." [Muslim] Al-'Irbad Ibn Sariyya
