عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: خَرَجْنَا بِالْحَجِّ فَلَمَّا قَدِمْنَا مَكَّةَ أَمَرَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنْ نَجْعَلَهَا عُمْرَةً وَقَالَ: ((لَوِ اسْتَقْبَلْتُ مِنْ أَمْرِي مَا اسْتَدْبَرْتُ لَجَعَلْتُهَا عُمْرَةً وَلَكِنِّي سُقْتُ الْهُدْيَ وَقَرَنْتُ الْحَجَّ وَالْعُمْرَةَ))
It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, who says: We set out proclaiming the Talbiyah for Hajj, but when we reached Makkah Mukarramah, the Messenger of Allah, peace and blessings be upon him, commanded us to consider it as ‘Umrah. And the Prophet, peace and blessings be upon him, said: If the thought that has come to me now had come to me earlier, I would have also made it ‘Umrah, but I have brought the sacrificial animal with me and I have combined Hajj and ‘Umrah.
