The story of Hajar is one of faith, resilience, and trust in Allah. Left alone in the desert with her infant son, she remained steadfast, and through her struggle, Allah provided the Zamzam Well, a source of life and mercy that flows till this day. This treatise explores Hajar’s journey, drawing from the Quran and Sunnah, with insights from scholars Al-Hafiz Ibn Hajr, Al-Allamah Ibn Baz, Al-Allamah Ibn Al-Uthaymin, and Al-Allamah Al-Sa’di . It also touches on the history of Zamzam and the Ka‘bah’s construction, showing how Hajar’s story is deeply connected to Islam’s sacred heritage.
