‘Ubadah bin ‘Abbad al-Muhallabi reports: In our Muhallab tribe, there is a woman who became a grandmother at the age of eighteen. She gave birth to a daughter at the age of nine, and her daughter also gave birth to her own daughter at the age of nine. Thus, that woman became a grandmother at the age of eighteen.
