What is the ruling of Islamic law on disseminating sayings and phrases of disbelievers? Is it permissible to do so based on the principle that "wisdom is the believer's lost property" and the saying, "And let not the hatred of a people prevent you from being just," given that the disseminator knows that his true role models are the Prophet (peace be upon him) and his Companions? And how do we respond to those who believe that there are sufficient and complete role models among Muslims that render it unnecessary to emulate others?

Scholars continue to transmit from the wisdom of the ancients what is appropriate to convey and what brings great benefit. The Prophet (peace be upon him) permitted speaking about the Children of Israel, and he said to Abu Hurayrah concerning Satan, "He spoke the truth to you, though he is a great liar." He also said, "Wisdom is the lost property of the believer."

However, this is conditioned upon its conformity with Islamic law. It is more appropriate to quote the words of Allah, His Messenger, the Companions, and the Successors. One must be wary of quoting the words of disbelievers and transgressors, or those known for a false principle, due to the corrupting effects therein.

As for the examples mentioned by the questioner: - The saying of Labid: "Verily, everything besides Allah is false": Labid embraced Islam and his Islam was good. It is probable that he said this after his conversion, so there is no evidence against it. - The story of Khalid ibn al-Walid and his brother's letter: This was narrated by Al-Waqidi, who is abandoned in Hadith. His shaykh, Yahya ibn al-Mughirah, was not authenticated by anyone, and his father, Al-Mughirah, did not live to see Khalid. Thus, the narration is mursal (lacks a link) and weak. - The Prophet's (peace be upon him) praise of Suhayl ibn Amr: The questioner did not provide evidence for this.
