Hadith 10:121
Abu Salama said he asked ‘A’isha how much the Prophet had given as dower, and she replied that his dower to his wives was twelve uqiyas * and a nashsh . She asked whether he knew what a nashsh was, and when he replied that he did not, she said it was half an uqiya ; so the total was five hundred dirhams. * The uqiya was 40 dirhams. Muslim transmitted it. Nashsh is in the nominative in Sharh as-sunna and all the sources.
وَعَنْ أَبِي سَلَمَةَ قَالَ: سَأَلْتُ عَائِشَةَ: كَمْ كَانَ صَدَاقُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَت: كَانَ صداقه لأزواجه اثْنَتَيْ عَشْرَةَ أُوقِيَّةً وَنَشٌّ قَالَتْ: أَتَدْرِي مَا النَّشٌّ؟ قُلْتُ: لَا قَالَتْ: نِصْفُ أُوقِيَّةٍ فَتِلْكَ خَمْسُمِائَةِ دِرْهَمٍ. رَوَاهُ مُسْلِمٌ. وَنَشٌّ بِالرَّفْعِ فِي شَرْحِ السّنة وَفِي جَمِيع الْأُصُول
