عن أُمِّ ورَقة بنت عبد الله بن الحارث الأنصارية، أنها كانت قد جَمعت القرآن، وكان النبي صلى الله عليه وسلم قد أَمَرَهَا أن تَؤُمَّ أهل دارِها، وكان لها مُؤَذِّنٌ، وكانت تَؤُمُّ أهل دارها.
[حسن] - [رواه أبو داود وأحمد]

Umm Waraqah bint ‘Abdullāh ibn al-Hārith al-Ansāri reported that she had memorized the Qur'an, and the Prophet (may Allah's peace and blessings be upon him) ordered her to lead her household in prayers. There was a Muezzin for her, and she used to lead her household in prayer.

Explanation

Umm Waraqah al-Ansāriyyah (may Allah be pleased with her) had memorized the Qur'an by heart, and the Prophet (may Allah's peace and blessings be upon him) ordered her to lead her household in the five daily prayers. There was a Muezzin for her to call for the five daily prayers, and she used to lead her female household in prayer, as mentioned in the narration of Ad-Daraqutni. Thus, the Hadīth proves that she was leading exclusively the women in prayer.
