It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) concerning the saying of Allah Almighty: "Then fight the leaders of disbelief" [Surah al-Tawbah: 12] , that he said: "(It refers to) Abu Jahl bin Hisham, Umayyah bin Khalaf, Utbah bin Rabi'ah, Abu Sufyan bin Harb and Suhayl bin Amr. They are the ones who broke the covenant of Allah and intended to expel the Messenger of Allah (peace and blessings be upon him) from Makkah." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), and they did not record it.

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When you see a man who is devoted to the mosque, then do not hesitate to bear witness that he is a believer, for Allah Almighty says: 'The mosques of Allah are only maintained by those who believe in Allah' [Surah al-Tawbah: 18] ." This hadith is sahih in its chain, and the two Shaykhs did not record it.
