Arabic hadith text
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم قَالَتْ فِي الْمَرْأَةِ الْحَامِلِ تَرَى الدَّمَ أَنَّهَا تَدَعُ الصَّلاَةَ .
Translation
Yahya related to me from Malik that he had heard that A'isha, thewife of the Prophet, may Allah bless him and grant him peace, saidthat a pregnant woman who noticed bleeding left off from prayer.
