[Machine] That the Messenger of Allah ﷺ said: "Hajj and Umrah are two obligatory acts of worship." I was informed by Abu Saad al-Zahid, who informed me that Abu al-Hasan Muhammad bin al-Hasan bin Ismail al-Darir narrated to him that Ja'far bin Muhammad al-Firiyabi narrated to him, who narrated from Qutaybah, who narrated from Ibn Lahiah, who mentioned it. And Ibn Lahiah is not considered a reliable source for this narration. And in the narration of Sabi ibn Ma'bad, he said to Umar ibn al-Khattab: "I found Hajj and Umrah written for me and I have performed them." Umar responded: "You have followed the Sunnah of your Prophet ﷺ ." And this is mentioned if Allah wills, in the chapter regarding Qarin, which refers to the sacrifice of an animal during Hajj and Umrah.  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْحَجُّ وَالْعُمْرَةُ فَرِيضَتَانِ وَاجِبَتَانِ حَدَّثَنَاهُ أَبُو سَعْدٍ الزَّاهِدُ أنبأ أَبُو الْحَسَنِ مُحَمَّدُ بْنُ الْحَسَنِ بْنِ إِسْمَاعِيلَ الضَّرِيرُ أنبأ جَعْفَرُ بْنُ مُحَمَّدٍ الْفِرْيَابِيُّ ثنا قُتَيْبَةُ ثنا ابْنُ لَهِيعَةَ فَذَكَرَهُ وَابْنُ لَهِيعَةَ غَيْرُ مُحْتَجٍّ بِهِ وَفِي حَدِيثِ الصَّبِيِّ بْنِ مَعْبَدٍ أَنَّهُ قَالَ لِعُمَرَ بْنِ الْخَطَّابِ ؓ إِنِّي وَجَدْتُ الْحَجَّ وَالْعُمْرَةَ مَكْتُوبَيْنِ عَلَيَّ وَإِنِّي أَهْلَلْتُ بِهِمَا فَقَالَ هُدِيتَ لِسُنَّةِ نَبِيِّكَ ﷺ وَذَلِكَ يَرِدُ إِنْ شَاءَ اللهُ فِي بَابِ الْقَارِنِ يُهْرِيقُ دَمًا
