[Machine] The obligation of Hajj was revealed to the Prophet ﷺ after his migration, and the Messenger of Allah ﷺ opened Mecca in the month of Ramadan and left it in Shawwal. At that time, he appointed 'Attab ibn Asid as its governor. He established the Hajj for the Muslims by the order of the Messenger of Allah ﷺ. The Messenger of Allah ﷺ was in Medina and was capable of performing Hajj along with his wives and most of his companions.

Later, the Messenger of Allah ﷺ left for Tabuk and sent Abu Bakr to lead the Hajj for the people in the ninth year. The Messenger of Allah ﷺ was still in Medina and was capable of performing Hajj, but he did not perform it, nor did his wives or any of his companions until he performed it in the tenth year.

Based on this, we deduced that performing Hajj is obligatory once in a lifetime, with the condition of reaching puberty, and it should be done before death. The Sheikh (scholar) mentioned that this is also mentioned in the reports and historical accounts.

As for the mention of the revelation of the obligation of Hajj after migration, as the Shafi'i scholars have mentioned, our companions have derived it from the Hadith of Ka'b ibn 'Ujrah, indicating that it was revealed during the time of Hudaybiyah.  

نَزَلَتْ فَرِيضَةُ الْحَجِّ عَلَى النَّبِيِّ ﷺ بَعْدَ الْهِجْرَةِ وَافْتَتَحَ رَسُولُ اللهِ ﷺ مَكَّةَ فِي شَهْرِ رَمَضَانَ وَانْصَرَفَ عَنْهَا فِي شَوَّالٍ وَاسْتُخْلِفَ عَلَيْهَا عَتَّابُ بْنُ أَسِيدٍ فَأَقَامَ الْحَجَّ لِلْمُسْلِمِينَ بِأَمْرِ رَسُولِ اللهِ ﷺ وَرَسُولُ اللهِ ﷺ بِالْمَدِينَةِ قَادِرٌ عَلَى أَنْ يَحُجَّ وَأَزْوَاجُهُ وَعَامَّةُ أَصْحَابِهِ ثُمَّ انْصَرَفَ رَسُولُ اللهِ ﷺ عَنْ تَبُوكَ فَبَعَثَ أَبَا بَكْرٍ فَأَقَامَ الْحَجَّ لِلنَّاسِ سَنَةَ تِسْعٍ وَرَسُولُ اللهِ ﷺ بِالْمَدِينَةِ قَادِرٌ عَلَى أَنْ يَحُجَّ لَمْ يَحُجَّ هُوَ وَلَا أَزْوَاجُهُ وَلَا أَحَدٌ مِنْ أَصْحَابِهِ حَتَّى حَجَّ سَنَةَ عَشْرٍ فَاسْتَدْلَلْنَا عَلَى أَنَّ الْحَجَّ فَرْضُهُ مَرَّةٌ فِي الْعُمُرِ أَوَّلُهُ الْبُلُوغُ وَآخِرُهُ أَنْ يَأْتِيَ بِهِ قَبْلَ مَوْتِهِ قَالَ الشَّيْخُ وَهَذَا الَّذِي ذَكَرَهُ الشَّافِعِيُّ رَحِمَهُ اللهُ مَوْجُودٌ فِي الْأَخْبَارِ وَالتَّوَارِيخِ أَمَّا مَا ذَكَرَهُ مِنْ نُزُولِ فَرِيضَةِ الْحَجِّ بَعْدَ الْهِجْرَةِ فَكَمَا قَالَ وَاسْتَدَلَّ أَصْحَابُنَا بِحَدِيثِ كَعْبِ بْنِ عُجْرَةَ عَلَى أَنَّهَا نَزَلَتْ زَمَنَ الْحُدَيْبِيَةِ  

[Machine] The Messenger of Allah ﷺ stood beside me in Hudaybiyah while I had lice on my head. He asked, "Do your lice bother you?" I replied, "Yes, O Messenger of Allah." He said, "Shave your head." He also mentioned the verse starting with "So whoever among you is ill or has an ailment in his scalp" until the end of the verse. Then the Messenger of Allah ﷺ said, "Fast for three days, or give charity or offer sacrifice as compensation."  

قَالَ وَقَفَ عَلَيَّ رَسُولُ اللهِ ﷺ بِالْحُدَيْبِيَةِ وَرَأْسِي يَتَهَافَتُ قَمْلًا فَقَالَ أَتُؤْذِيكَ هَوَامُّكَ؟ قُلْتُ نَعَمْ يَا رَسُولَ اللهِ قَالَ فَاحْلِقْ رَأْسَكَ أَوْ قَالَ فَاحْلِقْ قَالَ فَفِيَّ نَزَلَتْ هَذِهِ الْآيَةُ {فَمَنْ كَانَ مِنْكُمْ مَرِيضًا أَوْ بِهِ أَذًى مِّنْ رَأْسِهِ فَفِدْيَةٌ مِنْ صِيَامٍ أَوْ صَدَقَةٍ أَوْ نُسُكٍ} [البقرة 196] إِلَى آخِرِهَا فَقَالَ رَسُولُ اللهِ ﷺ صُمْ ثَلَاثَةَ أَيَّامٍ أَوْ تَصَدَّقْ بِفَرَقٍ بَيْنَ سِتَّةٍ أَوِ انْسُكْ بِمَا تَيَسَّرَ  

[Machine] And from some of the companions of the Messenger of Allah ﷺ , regarding his statement, "And complete Hajj and Umrah for Allah" [Al-Baqarah 196], he says: Establish Hajj and Umrah for Allah.  

وَعَنْ نَاسٍ مِنْ أَصْحَابِ رَسُولِ اللهِ ﷺ وَأَمَّا قَوْلُهُ {وَأَتِمُّوا الْحَجَّ وَالْعُمْرَةَ لِلَّهِ} [البقرة 196] فَيَقُولُ أَقِيمُوا الْحَجَّ وَالْعُمْرَةَ لِلَّهِ  

[Machine] The Sheikh and the time of Hudaybiyah was the sixth year of the Hijrah in the month of Dhul-Qa'dah.  

الشَّيْخُ وَزَمَنُ الْحُدَيْبِيَةِ كَانَ سَنَةَ سِتٍّ مِنَ الْهِجْرَةِ فِي ذِي الْقَعْدَةِ  

[Machine] The Battle of Hudaibiya took place in the sixth year after the Prophet's migration to Medina, in the month of Dhu al-Qa'da. The Treaty of Hudaibiya took place in the month of Dhu al-Qa'da in the seventh year. The conquest of Mecca took place in the month of Ramadan in the eighth year. Then, the Prophet ﷺ went out from there to Hunayn and Taif. When he returned in the month of Shawwal, he performed Umrah from Ji'ranah. Then, Attab bin Asid performed Hajj and the Messenger of Allah ﷺ used his Hajj as a model for the people. Abu Bakr performed Hajj in the ninth year, following the example of the Prophet ﷺ. Then, the Prophet ﷺ performed Hajj in the tenth year after his migration to Medina, which is known as the Farewell Pilgrimage. This indicates that the order of conquest, the use of Attab bin Asid's Hajj, followed by Abu Bakr's in the ninth year, and then the Prophet's in the tenth year, is as mentioned by Imam Shafi'i, may Allah have mercy on him. This is well-known among the people of military expeditions and is mentioned in the connected narrations separately.  

كَانَتِ الْحُدَيْبِيَةُ سَنَةَ سِتٍّ بَعْدَ مَقْدِمِ النَّبِيِّ ﷺ الْمَدِينَةَ فِي ذِي الْقَعْدَةِ وَكَانَتِ الْقَضِيَّةُ فِي ذِي الْقَعْدَةِ سَنَةَ سَبْعٍ وَكَانَ الْفَتْحُ فِي رَمَضَانَ سَنَةَ ثَمَانٍ ثُمَّ خَرَجَ النَّبِيُّ ﷺ مِنْ فَوْرِهِ إِلَى حُنَيْنٍ وَالطَّائِفِ فَلَمَّا رَجَعَ فِي شَوَّالٍ اعْتَمَرَ مِنَ الْجِعْرَانَةِ ثُمَّ حَجَّ عَتَّابُ بْنُ أَسِيدٍ فَأَقَامَ لِلنَّاسِ الْحَجَّ اسْتَعْمَلَهُ رَسُولُ اللهِ ﷺ عَلَى الْحَجِّ ثُمَّ حَجَّ أَبُو بَكْرٍ سَنَةَ تِسْعٍ اسْتَعْمَلَهُ النَّبِيُّ ﷺ ثُمَّ حَجَّ النَّبِيُّ ﷺ سَنَةَ عَشْرٍ مِنْ مَقْدِمِهِ الْمَدِينَةَ وَهِيَ حَجَّةُ الْوَدَاعِ وَفِي هَذَا دَلَالَةٌ عَلَى أَنَّ أَمْرَ الْفَتْحِ وَاسْتِعْمَالَ عَتَّابِ بْنِ أَسِيدٍ ثُمَّ اسْتِعْمَالُ أَبِي بَكْرٍ فِي سَنَةِ تِسْعٍ ثُمَّ حَجُّهُ سَنَةَ عَشْرٍ مَا قَالَهُ الشَّافِعِيُّ رَحِمَهُ اللهُ وَهُوَ مَشْهُوَرٌ فِيمَا بَيْنَ أَهْلِ الْمَغَازِي مَذْكُورٌ فِي الْأَحَادِيثِ الْمَوْصُولَةِ مُفَرَّقًا  

[Machine] I asked Anas ibn Malik how many times did the Prophet ﷺ perform Hajj? He said, he performed Hajj once and he performed Umrah four times. The first Umrah was the one that the polytheists prevented him from entering the Kaaba, and the second Umrah was when they made peace with him, so he returned later that year. He also performed Umrah from Ji'ranah when he distributed the spoils of the Battle of Hunayn in the month of Dhul-Qa'dah, and he performed Hajj with Umrah together.  

قُلْتُ لِأَنَسِ بْنِ مَالِكٍ كَمْ مِنْ حَجَّةٍ حَجَّهَا النَّبِيُّ ﷺ؟ قَالَ حَجَّةٌ وَاحِدَةٌ وَاعْتَمَرَ أَرْبَعَ عُمَرٍ عُمْرَتُهُ الَّتِي صَدَّهُ الْمُشْرِكُونَ عَنِ الْبَيْتِ وَالْعُمْرَةُ الثَّانِيَةُ حِينَ صَالَحُوهُ فَرَجَعَ مِنَ الْعَامِ الْمُقْبِلِ وَعُمْرَةٌ مِنَ الْجِعْرَانَةِ حِينَ قَسَمَ غَنِيمَةَ حُنَيْنٍ فِي ذِي الْقَعْدَةِ وَحَجَّةٌ مَعَ عُمْرَتِهِ  

[Machine] The Messenger of Allah ﷺ participated in nineteen battles and performed Hajj once after emigrating, and he did not perform another Hajj after that except for the Farewell Hajj. Abu Ishaq said: "He (the Prophet) also performed another Hajj in Makkah." Al-Bukhari mentioned this in his Sahih (authentic book) through the narration of Amru bin Khalid, and Muslim also narrated it from another perspective through the narration of Zuhayr.  

أَنَّ رَسُولَ اللهِ ﷺ غَزَا تِسْعَ عَشْرَةَ غَزْوَةً وَأَنَّهُ حَجَّ بَعْدَمَا هَاجَرَ حَجَّةً وَاحِدَةً لَمْ يَحُجَّ بَعْدَهَا حَجَّةً إِلَّا حَجَّةَ الْوَدَاعِ قَالَ أَبُو إِسْحَاقَ وَبِمَكَّةَ أُخْرَى وَأَخْرَجَهُ الْبُخَارِيُّ فِي الصَّحِيحِ عَنْ عَمْرِو بْنِ خَالِدٍ وَأَخْرَجَهُ مُسْلِمٌ مِنْ وَجْهٍ آخَرَ عَنْ زُهَيْرٍ  

[Machine] The Messenger of Allah ﷺ performed three Hajj pilgrimages: two while he was in Makkah before the migration, and one was the Farewell Hajj. The scholar said, "The Hajj before the migration is performed before the obligatory Hajj is revealed, so it cannot be considered as a replacement for the obligatory Hajj that is revealed after it. And Allah knows best."  

حَجَّ رَسُولُ اللهِ ﷺ ثَلَاثَ حِجَجٍ حَجَّتَيْنِ وَهُوَ بِمَكَّةَ قَبْلَ الْهِجْرَةِ وَحَجَّةَ الْوَدَاعِ قَالَ الشَّيْخُ وَحَجَّةً قَبْلَ الْهِجْرَةِ يَكُونُ قَبْلَ نُزُولِ فَرْضِ الْحَجِّ فَلَا يُعْتَدُّ بِهِ عَنِ الْفَرْضِ الْمُنْزَلِ بَعْدَهُ وَاللهُ أَعْلَمُ
