حَدَّثَنَا هَدَّابُ بْنُ خَالِدٍ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا قَتَادَةُ، أَنَّ أَنَسًا، - رضى الله عنه - أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم اعْتَمَرَ أَرْبَعَ عُمَرٍ كُلُّهُنَّ فِي ذِي الْقَعْدَةِ إِلاَّ الَّتِي مَعَ حَجَّتِهِ عُمْرَةً مِنَ الْحُدَيْبِيَةِ أَوْ زَمَنَ الْحُدَيْبِيَةِ فِي ذِي الْقَعْدَةِ وَعُمْرَةً مِنَ الْعَامِ الْمُقْبِلِ فِي ذِي الْقَعْدَةِ وَعُمْرَةً مِنْ جِعْرَانَةَ حَيْثُ قَسَمَ غَنَائِمَ حُنَيْنٍ فِي ذِي الْقَعْدَةِ وَعُمْرَةً مَعَ حَجَّتِهِ‏.‏
