حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ، حَدَّثَنَا سَلَمَةُ بْنُ عَلْقَمَةَ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، قَالَ تُوُفِّيَ ابْنٌ لأُمِّ عَطِيَّةَ ـ رضى الله عنها ـ فَلَمَّا كَانَ الْيَوْمُ الثَّالِثُ دَعَتْ بِصُفْرَةٍ، فَتَمَسَّحَتْ بِهِ وَقَالَتْ نُهِينَا أَنْ نُحِدَّ أَكْثَرَ مِنْ ثَلاَثٍ إِلاَّ بِزَوْجٍ.
