bayhaqi:12583Abū ʿAbdullāh al-Ḥāfiẓ > ʿAbd al-Raḥman b. al-Ḥasan al-Qāḍī > Ibrāhīm b. al-Ḥusayn > Ādam b. Abū Iyās > And Rqāʾ > Ibn Abū Najīḥ

[Machine] About Mujahid's saying, {And let them fear who, if they left behind them weak offspring} [Al-Nisa 9]. He said, this is said during the will when someone says to the person attending, "You have reduced it, so make a bequest for so-and-so and the family of so-and-so." Allah says, {And let them fear} [Al-Nisa 9]. These people {And let them speak} [Al-Nisa 9] as they love to be said about them concerning their children after them, {And let them speak a word of justice} [Al-Nisa 9], meaning fairness.
