Jabir said that when God’s Messenger preached his eyes became red, his voice rose and his anger became violent, so that he was like one warning an army and saying, “The enemy has made a morning attack on you.” “The enemy has made an evening attack on you.” He would Say, “The last hour and I have been sent like these two,” and he would join his forefinger and his middle finger.
‘Ammar told how he heard God’s Messenger say, “The length of a man’s prayer and the shortness of his sermon are a sign of his understanding, so make the prayer long and the sermon short, for there is magic in eloquence.”
Jabir b. Samura said the Prophet gave two sermons between which he sat, recited the Qur’an and gave the people an exhortation and both his prayer and his sermon were of moderate length.
