It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that one day some people were at the door of the Messenger of Allah (peace and blessings be upon him) disputing about the Qur'an. The Prophet (peace and blessings be upon him) came out with the colour of his (peace and blessings be upon him) face changed, and he (peace and blessings be upon him) said: "O people! It is by this that the nations before you were destroyed. Indeed, one part of the Qur'an confirms another, so do not deny one part of it by means of another."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Salih bin Abi al-Akhdar narrated this hadith from al-Zuhri, from Ubaydullah bin Abdullah, and Ma'mar narrated it from al-Zuhri, from Amr bin Shu'ayb, from his father, from his grandfather."
This is how it appears in the Dar al-Haramayn printed edition, and probably there is a scribal error in it; the correct form is (al-Sulaymi).
