Sahih Muslim
وَحَدَّثَنِيهِ عَلِيُّ بْنُ خَشْرَمٍ، أَخْبَرَنَا عِيسَى بْنُ يُونُسَ، عَنِ ابْنِ جُرَيْجٍ، بِهَذَا الإِسْنَادِ وَفِي رِوَايَتِهِ قَالَتْ لاَ أَىْ بُنَىَّ إِنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم أَذِنَ لِظُعُنِهِ .
This hadith has been narrated by Ibn Juraij with the same chain of transmitters, and In his narration (the words are): " She (Asma') said: My son, Allah's Apostle (ﷺ) granted permission to women."
