أَخْبَرَنَا مُحَمَّدُ بْنُ يَزِيدَ الْبَزَّازُ ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ ، عَنْ أَبِي إِسْحَاق ، عَنْ زَيْدِ بْنِ يُثَيْعٍ ، قَالَ : سَأَلْنَا عَلِيًّا : بِأَيِّ شَيْءٍ بُعِثْتَ؟.
قَالَ : " بُعِثْتُ بِأَرْبَعٍ :لَا يَدْخُلُ الْجَنَّةَ إِلَّا نَفْسٌ مُؤْمِنَةٌ، وَلَا يَطُوفُ بِالْبَيْتِ عُرْيَانٌ، وَلَا يَجْتَمِعُ مُسْلِمٌ وَكَافِرٌ فِي الْحَجِّ بَعْدَ عَامِهِمْ هَذَا، وَمَنْ كَانَ بَيْنَهُ وَبَيْنَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَهْدٌ، فَعَهْدُهُ إِلَى مُدَّتِهِ، وَمَنْ لَمْ يَكُنْ لَهُ عَهْدٌ، فَهِيَ أَرْبَعَةُ أَشْهُرٍ.
يَقُولُ بَعْدَ يَوْمِ النَّحْرِ أَجَلُهُمْ عِشْرِينَ مِنْ ذِي الْحِجَّةِ، فَاقْتُلُوهُمْ بَعْدَ الْأَرْبَعَةِ "

Muhammad bin Yazid Al-Bazzaz told us, Sufyan bin Uyaynah told us, on the authority of Abu Ishaq, on the authority of Zayd bin Yatha’, he said: We asked Ali: With what were you sent?
He said: “I was sent with four things: No one will enter Paradise except a believing soul, no naked person will circumambulate the Kaaba, and no Muslim and an unbeliever will meet in Hajj after the Hajj.” This is their year, and whoever has a covenant with the Messenger of God, may God bless him and grant him peace, then his covenant lasts for its duration, and whoever does not have a covenant, then it is Four months.
He says, “After the Day of Sacrifice, their deadline is twenty days of Dhul-Hijjah, so kill them after the four.”
