Mishkat al-Masabih, 3490, 3491

'Abdallah b. ‘Amr reported God's Messenger as saying, “The blood wit for unintentional murder which resembles intentional, such as is done with a whip and a stick, is a hundred camels, forty of which are pregnant.” Nasa'i, Ibn Majah and Darimi transmitted it, and Abu Dawud transmitted it both on his authority and on that of Ibn ‘Umar. <i>Sharh as-sunna</i> has the wording in <i>al-Masabih</i> on the authority of Ibn ‘Umar.

عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ:

أَلَا إِنَّ دِيَةَ الْخَطَأِ شِبْهِ الْعَمْدِ مَا كَانَ بِالسَّوْطِ وَالْعَصَا مِائَةٌ مِنَ الإِبلِ: مِنْهَا أربعونَ فِي بطونِها أولادُها

. رَوَاهُ النسائيُّ وَابْن مَاجَه والدارمي وَرَوَاهُ أَبُو دَاوُد عَنهُ وَابْن مَاجَه وَعَن ابْن عمر. وَفِي «شَرْحِ السُّنَّةِ» لَفْظُ «الْمَصَابِيحِ» عَنِ ابْنِ عمر
