Hagar was unwanted, but she reappears in the Torah as Ketura. See Bereishis 25:
1. And Abraham took another wife and her name was Keturah.
א. וַיֹּסֶף אַבְרָהָם וַיִּקַּח אִשָּׁה וּשְׁמָהּ קְטוּרָה:
Keturah: (Gen. Rabbah 61:4) This is Hagar. She was called Keturah because her deeds were as beautiful as incense (קְטֹרֶת), and because she tied (קָטְרָה, the Aramaic for“tied”) her opening, for she was not intimate with any man from the day she separated from Abraham.
קטורה: זו הגר, ונקראת קטורה על שם שנאים מעשיה כקטרת ושקשרה פתחה שלא נזדווגה לאדם מיום שפרשה מאברהם:
ortivika wrote:I had a dream today. In this dream i saw arabs evacuated from the territory of Har haBait. The point was that i tried to take some girl whose name was Hagar from them. And i remember very clearly that i told "this girl must be with jewish people now".
Do you know smth. about Hagar in Aharit hayamim?
