(And We know well that they say: Only a man teacheth him. The speech of him at whom they falsely hint is outlandish…) [16:103]. Abu Nasr Ahmad ibn Ibrahim al-Muzakki> Abu ‘Abd Allah Muhammad ibn Hamdan al-Zahid> ‘Abd Allah ibn Muhammad ibn ‘Abd al-‘Aziz> Abu Hisham al-Rifa‘i> Ibn Fudayl> Husayn> ‘Abd Allah ibn Muslim who said: “We owned two Christian youths from the people of ‘Ayn Tamr, one called Yasar and the other Jabr. Their trade was making swords but they also could read the Scriptures in their own tongue. The Messenger of Allah, Allah bless him and give him peace, used to pass by them and listen to their reading. As a result, the idolaters used to say: ‘He is being taught by them!’ To give them the lie, Allah, exalted is He, revealed (The speech of him at whom they falsely hint is outlandish, and this is clear Arabic speech)”.
