عَنْ أَبِي نُعَيْمٍ قَالَ حَدَّثَنَا الْوَلِيدُ قَالَ حَدَّثَتْنِي جَدَّتِي عَنْ أُمِّ وَرَقَةَ بِنْتِ عَبْدِ اللَّهِ بْنِ الْحَارِثِ الْأَنْصَارِيِّ وَكَانَتْ قَدْ جَمَعَتِ الْقُرْآنَ وَكَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَدْ أَمَرَهَا أَنْ تُؤُمَّ أَهْلَ دَارِهَا وَكَانَ لَهَا مُؤَذِّنٌ وَكَانَتْ تُؤُمُّ أَهْلَ دَارِهَا
Sayyida Umm Waraqah (may Allah be pleased with her) narrates that she had memorized the Holy Qur'an, so the Noble Prophet (peace and blessings of Allah be upon him) instructed her to lead her household in prayer. Thus, she had a muezzin and she used to lead her household in prayer.
