The people (of the Pre-Islamic Period) used to think that to perform ʿUmra during the months of Hajj was one of the major sins on earth. And also used to consider the month of Safar as a forbidden (i.e. sacred) month and they used to say, "When the wounds of the camel's back heal up (after they return from Hajj) and the signs of those wounds vanish and the month of Safar passes away then (at that time) ʿUmra is permissible for the one who wishes to perform it." In the morning of the 4th of Dhul- Hijja, the Prophet ﷺ and his companions reached Mecca, assuming Ihram for Hajj and he ordered his companions to make their intentions of the Ihram for ʿUmra only (instead of Hajj) so they considered his order as something great and were puzzled, and said, "O Messenger of Allah ﷺ! What kind (of finishing) of Ihram is allowed?" The Prophet ﷺ replied, "Finish the Ihram completely like a non-Muhrim (you are allowed everything)."  

أَنَّ الْعُمْرَةَ فِي أَشْهُرِ الْحَجِّ مِنْ أَفْجَرِ الْفُجُورِ فِي الأَرْضِ وَيَجْعَلُونَ الْمُحَرَّمَ صَفَرًا وَيَقُولُونَ إِذَا بَرَأَ الدَّبَرْ وَعَفَا الأَثَرْ وَانْسَلَخَ صَفَرْ حَلَّتِ الْعُمْرَةُ لِمَنِ اعْتَمَرْ قَدِمَ النَّبِيُّ ﷺ وَأَصْحَابُهُ صَبِيحَةَ رَابِعَةٍ مُهِلِّينَ بِالْحَجِّ فَأَمَرَهُمْ أَنْ يَجْعَلُوهَا عُمْرَةً فَتَعَاظَمَ ذَلِكَ عِنْدَهُمْ فَقَالُوا يَا رَسُولَ اللَّهِ أَىُّ الْحِلِّ قَالَ حِلٌّ كُلُّهُ  

The people used to consider the performance of ʿUmra in the months of Hajj an evil deed on the earth, and they used to call the month of Muharram as Safar and used to say, "When (the wounds over) the backs (of the camels) have healed and the foot-marks (of the camels) have vanished (after coming from Hajj), then ʿUmra becomes legal for the one who wants to perform ʿUmra." Messenger of Allah ﷺ and his companions reached Mecca assuming Ihram for Hajj on the fourth of Dhul-Hijja. The Prophet ﷺ ordered his companions to perform ʿUmra (with that lhram instead of Hajj). They asked, "O Allah's Apostle! What kind of finishing of Ihram?" The Prophet ﷺ said, "Finish the Ihram completely.'  

أَنَّ الْعُمْرَةَ فِي أَشْهُرِ الْحَجِّ مِنَ الْفُجُورِ فِي الأَرْضِ وَكَانُوا يُسَمُّونَ الْمُحَرَّمَ صَفَرًا وَيَقُولُونَ إِذَا بَرَا الدَّبَرْ وَعَفَا الأَثَرْ حَلَّتِ الْعُمْرَةُ لِمَنِ اعْتَمَرْ قَالَ فَقَدِمَ رَسُولُ اللَّهِ ﷺ وَأَصْحَابُهُ رَابِعَةً مُهِلِّينَ بِالْحَجِّ وَأَمَرَهُمُ النَّبِيُّ ﷺ أَنْ يَجْعَلُوهَا عُمْرَةً قَالُوا يَا رَسُولَ اللَّهِ أَىُّ الْحِلِّ قَالَ الْحِلُّ كُلُّهُ  

When the backs of their camels would become all right and traces (if the pilgrims) would be effaced (from the paths) and the month of Safar would be over, then Umra would be permissible for one who wants to perform it. When Allah's Apostle ﷺ and his Companions came in the state of Ihram for performing Hajj on the fourth (of Dhu'l-Hijja) he (Allah's Apostle) commanded them to change their state of Ihram (from Hajj) to that of 'Umra. It was something inconceivable for them. So they said: Messenger of Allah, is it a complete freedom (of the obligation) of Ihram? Thereupon he said: It is a complete freedom (from Ihram).  

أَنَّ الْعُمْرَةَ فِي أَشْهُرِ الْحَجِّ مِنْ أَفْجَرِ الْفُجُورِ فِي الأَرْضِ وَيَجْعَلُونَ الْمُحَرَّمَ صَفَرً وَيَقُولُونَ إِذَا بَرَأَ الدَّبَرْ وَعَفَا الأَثَرْ وَانْسَلَخَ صَفَرْ حَلَّتِ الْعُمْرَةُ لِمَنِ اعْتَمَرْ فَقَدِمَ النَّبِيُّ ﷺ وَأَصْحَابُهُ صَبِيحَةَ رَابِعَةٍ مُهِلِّينَ بِالْحَجِّ فَأَمَرَهُمْ أَنْ يَجْعَلُوهَا عُمْرَةً فَتَعَاظَمَ ذَلِكَ عِنْدَهُمْ فَقَالُوا يَا رَسُولَ اللَّهِ أَىُّ الْحِلِّ قَالَ الْحِلُّ كُلُّهُ

كَانُوا يَرَوْنَ الْعُمْرَةَ فِي أَشْهُرِ الْحَجِّ مِنْ أَفْجَرِ الْفُجُورِ فِي الْأَرْضِ وَيَجْعَلُونَ الْمُحَرَّمَ صَفَرًا وَيَقُولُونَ إِذَا بَرَأَ الدَّبَرْ وَعَفَا الْأَثَرْ وَانْسَلَخَ صَفَرْ حَلَّتِ الْعُمْرَةُ لِمَنِ اعْتَمَرْ فَلَمَّا قَدِمَ النَّبِيُّ ﷺ وَأَصْحَابُهُ لِصَبِيحَةِ رَابِعَةٍ مُهِلِّينَ بِالْحَجِّ فَأَمَرَهُمْ أْنْ يَجْعَلُوهَا عُمْرَةً فَتَعَاظَمَ ذَلِكَ عِنْدَهُمْ فَقَالُوا يَا رَسُولَ اللهِ أَيُّ الْحِلِّ؟ قَالَ الْحِلُّ كُلُّهُ وَفِي كِتَابِهِ لِصُبْحٍ
