Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: On the occasion of the Conquest of Makkah (the narrator is in doubt; perhaps the words are:) on the occasion of the Battle of Hunayn, one thousand men from the Banu Sulaym took part alongside the Prophet (peace and blessings be upon him).
Al-Tabarani recorded it, and its narrators are the narrators of the Sahih, except for Yazid al-Nahwi and Abdullah bin Ahmad bin Hanbal, whose case is different; however, both of them are thiqah (trustworthy).
