"We asked 'Ali what he had been dispatched with during the Hajj. He said: 'I was sent with four: That there shall be no Tawaf around the House while naked, that if there is a treaty between someone and the Prophet ﷺ, then the treaty remains until its expiration, and whoever does not have a treaty, then he has the span of four months, none shall enter Paradise except a believer, and the idolaters and Muslims shall not congregate (for Hajj) after this year.'" (Using translation from Tirmidhī 3092)
سَأَلْنَا عَلِيًّا بِأَيِّ شَيْءٍ بُعِثْتَ فِي الْحَجَّةِ قَالَ بُعِثْتُ بِأَرْبَعٍ لَا يَدْخُلُ الْجَنَّةَ إِلَّا نَفْسٌ مُؤْمِنَةٌ وَلَا يَطُوفُ بِالْبَيْتِ عُرْيَانٌ وَلَا يَجْتَمِعُ مُؤْمِنٌ وَكَافِرٌ فِي الْمَسْجِدِ الْحَرَامِ بَعْدَ عَامِهِمْ هَذَا وَمَنْ كَانَ بَيْنَهُ وَبَيْنَ النَّبِيِّ ﷺ عَهْدٌ فَعَهْدُهُ إِلَى مُدَّتِهِ وَمَنْ لَمْ يَكُنْ لَهُ عَهْدٌ فَأَجَلُهُ أَرْبَعَةُ أَشْهُرٍ «صَحِيحٌ عَلَى شَرْطِ الشَّيْخَيْنِ وَلَمْ يُخَرِّجَاهُ» على شرط البخاري ومسلم
