Sahih al-Bukhari — Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh)) — Hadith No: 4838
Translation
Narrated `Abdullah bin `Amr bin Al-As:This Verse: 'Verily We have sent you (O Muhammad) as a witness, as a bringer of glad tidings and as a warner.' (48.8) which is in the Qur'an, appears in the Torah thus: 'Verily We have sent you (O Muhammad) as a witness, as a bringer of glad tidings and as a warner, and as a protector for the illiterates (i.e., the Arabs.) You are my slave and My Apostle, and I have named you Al-Mutawakkil (one who depends upon Allah). You are neither hard-hearted nor of fierce character, nor one who shouts in the markets. You do not return evil for evil, but excuse and forgive. Allah will not take you unto Him till He guides through you a crooked (curved) nation on the right path by causing them to say: "None has the right to be worshipped but Allah." With such a statement He will cause to open blind eyes, deaf ears and hardened hearts
