Ibn Kharijah said: When the news of the death of the Negus (al-Najashi) reached the Prophet (peace and blessings be upon him), he said: "Your brother has passed away." So he (peace and blessings be upon him) came out, and we formed rows behind him (peace and blessings be upon him), and we prayed, though we could not see anything.
