Mukhtasar Bukhari

Umm al-Mu'minin Aisha Siddiqa (may Allah be pleased with her) says in another narration that when the Prophet Muhammad (peace be upon him) fell ill and his illness intensified, he sought permission from his wives to be nursed in her house, so all of them granted permission.... The rest is the same as mentioned previously (see Book: The Statement of Adhan... Chapter: Up to what extent of illness should a sick person attend the congregation?).
