muslim:1136bYaḥyá b. Yaḥyá > Abū Maʿshar al-ʿAṭṭār > Khālid b. Dhakwān > Saʾalt al-Rubayyiʿ b. Muʿawwidh > Ṣawm ʿĀshūrāʾ

I asked Rubayyi' daugther of Mu'awwidh about fasting on the day of 'Ashura. Thereupon she said: The Messenger of Allah (may peace he upon him) sent his messenger to the villages of the Ansar, and the rest of the hadith is the same (but with this variation that one of the Companions) said:" We used to make toys out of wool and took (them to the mosque) along with us. When they (the children) asked us for food, we gave them these toys to play with, and these made them forgetful till they completed their fast."  

مسلم:١١٣٦bوَحَدَّثَنَاهُ يَحْيَى بْنُ يَحْيَى حَدَّثَنَا أَبُو مَعْشَرٍ الْعَطَّارُ عَنْ خَالِدِ بْنِ ذَكْوَانَ قَالَ سَأَلْتُ الرُّبَيِّعَ بِنْتَ مُعَوِّذٍ عَنْ صَوْمِ عَاشُورَاءَ قَالَتْ

بَعَثَ رَسُولُ اللَّهِ ﷺ رُسُلَهُ فِي قُرَى الأَنْصَارِ فَذَكَرَ بِمِثْلِ حَدِيثِ بِشْرٍ غَيْرَ أَنَّهُ قَالَ وَنَصْنَعُ لَهُمُ اللُّعْبَةَ مِنَ الْعِهْنِ فَنَذْهَبُ بِهِ مَعَنَا فَإِذَا سَأَلُونَا الطَّعَامَ أَعْطَيْنَاهُمُ اللُّعْبَةَ تُلْهِيهِمْ حَتَّى يُتِمُّوا صَوْمَهُمْ
