Umm Waraqa bint Nawfal reported,

When the Prophet ﷺ set out for the Battle of Badr, she said, "Messenger of Allah, give me permission to go on the expedition with you. I will tend to your sick, perhaps Allah will grant me martyrdom."He replied, "Stay in your home, for Allah will grant you martyrdom."She came to be called "the Martyr." She had memorized the Quran, and she asked the Prophet ﷺ for permission to appoint a muezzin in her home, and he gave her permission.She had a male slave and a female slave whom she had promised freedom upon her death. The two of them came to her at night and smothered her with a velvet cloak of hers until she died, then fled.In the morning, Umar stood before the people and said, "Whoever has any knowledge about these two, or has seen them, let him bring them forward." They were brought, and he ordered that they be crucified. They were the first persons crucified in Madinah.In another narration, the Messenger of Allah ﷺ used to visit her at her home. He appointed a muezzin to call the prayer for her and instructed her to lead the people of her household in prayer.Abdul-Rahman said, "I myself saw her muezzin as a very old man."

عن أم ورقة بنت نوفل

أن النبي ﷺ لما غزا بدرا قالت: يا رسول الله، ائذن لي في الغزو معك، أمرض مرضاكم لعل الله أن يرزقني شهادة، فقال: قري في بيتك فإن الله تعالى يرزقك الشهادة. قال: فكانت تسمى الشهيدة، قال: وكانت قرأت القرآن، فاستأذنت النبي ﷺ أن تتخذ في دارها مؤذنا فأذن لها. قال: وكانت قد دبرت غلاما لها وجارية، فقاما إليها بالليل فغماها بقطيفة لها حتى ماتت وذهبا، فأصبح عمر فقام في الناس، فقال: من عنده من هذين علم، أو من رآهما فليجى بهما، فأمر بهما فصلبا، فكانا أول مصلوب بالمدينة. وفي رواية: وكان رسول الله ﷺ يزورها في بيتها، وجعل لها مؤذنا يؤذن لها، وأمرها أن تؤم أهل دارها قال عبد الرحمن: فأنا رأيت مؤذنها شيخا كبيرا.
