Jami` at-Tirmidhi Book 43, Hadith 123
from his father, that 'Aishah was asked: "Did the Prophet (ﷺ) used to say any poetry?" She said: "He would say parables with the poetry of Ibn Rawahah, saying: 'News shall come to you from where you did not expect it.'"
that the Prophet (ﷺ) entered Makkah during 'Umratil-Qada and 'Abdullah bin Rawahah was walking in front of him reciting verses of poetry. "O tribes of disbelievers get out of his way - today we will strike you about its revelation; a strike that removes the heads from the shoulders - and makes the friend not concerned about his friend." 'Umar said to him: "O Ibn Rawahah! Before the Messenger of Allah (ﷺ), and in the sanctuary of Allah you utter poetry?" the Messenger of Allah (ﷺ) said: "Leave him O 'Umar! For it is quicker upon them than the raining arrow."
that the Prophet (ﷺ) said: "The best statement spoken by the Arab is the saying of Labid: 'Everything aside from Allah perishes.'"
