Give guidance to the people of Daus

Narrated Abu Huraira:

Tufail bin 'Amr Ad-Dausi and his companions came to the Prophet and said, "O Allah's Apostle! The people of the tribe of Daus disobeyed and refused to follow you; so invoke Allah against them."

Narrated Anas:

When the Prophet intended to write a letter to the ruler of the Byzantines, he was told that those people did not read any letter unless it was stamped with a seal. So, the Prophet got a silver ring-- as if I were just looking at its white glitter on his hand ---- and stamped on it the expression "Muhammad, Apostle of Allah".

Narrated 'Abdullah bin 'Abbas:

Allah's Apostle sent his letter to Khusrau and ordered his messenger to hand it over to the Governor of Bahrain who was to hand it over to Khusrau. So, when Khusrau read the letter he tore it. Said bin Al-Musaiyab said, "The Prophet then invoked Allah to disperse them with full dispersion, (destroy them (i.e. Khusrau and his followers) severely)".

Narrated Anas:

Whenever Allah's Apostle attacked some people, he would never attack them till it was dawn. If he heard the Adhan (i.e. call for prayer) he would delay the fight, and if he did not hear the Adhan, he would attack them immediately after dawn. We reached Khaibar at night.
