Waki’ narrated to us, Sufyan narrated to us, from ‘Abdullah ibn Muhammad ibn ‘Aqil, from al-Tufayl ibn Ubayy ibn Ka’b, from his father, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The *Rajifah* (the first blast of the Trumpet) has come, followed by the *Radifah* (the second blast of the Trumpet). Death has come with what is in it."
