وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، أَنَّهُ كَانَ يَرَى عَبْدَ اللَّهِ بْنَ عُمَرَ يُهْدِي فِي الْحَجِّ بَدَنَتَيْنِ بَدَنَتَيْنِ وَفِي الْعُمْرَةِ بَدَنَةً بَدَنَةً ‏.‏ قَالَ وَرَأَيْتُهُ فِي الْعُمْرَةِ يَنْحَرُ بَدَنَةً وَهِيَ قَائِمَةٌ فِي دَارِ خَالِدِ بْنِ أَسِيدٍ وَكَانَ فِيهَا مَنْزِلُهُ ‏.‏ قَالَ وَلَقَدْ رَأَيْتُهُ طَعَنَ فِي لَبَّةِ بَدَنَتِهِ حَتَّى خَرَجَتِ الْحَرْبَةُ مِنْ تَحْتِ كَتِفِهَا ‏.‏

He said, "I saw him sacrifice ananimal during an umra outside the house of Khalid ibn Usayd, where hewas staying. I saw him stick his spear in the throat of the animal hewas going to sacrifice until the spear came out under its shoulder."' Translation Not Available
