What was the language of Abraham (peace be upon him), where was he sent, to whom was he sent, do his people have any connection or lineage to the Arabs, and how did Ishmael become one of the Arabized Arabs (al-Musta'ribah)?

Ibrahim (peace be upon him) spoke Syriac and Hebrew, and was sent first to the people of Babylon, then he went to Syria and Hijaz. As for Ismail (peace be upon him), he spoke Arabic because he grew up among the Jurhum tribe, married from them, and learned their language. Thus, Quraish and our Prophet Muhammad (peace be upon him) were from his lineage.
