Al-Quran

Surah: At-Taubah, Ayah: 36

Indeed, the number of months with Allah is twelve [lunar] months in the register of Allah [from] the day He created the heavens and the earth; of these, four are sacred. That is the correct religion, so do not wrong yourselves during them. And fight against the disbelievers collectively as they fight against you collectively. And know that Allah is with the righteous [who fear Him].

Hadith on Hajj

Narrated `Amra bint `Abdur-Rahman:I heard `Aisha saying, "Five days before the end of Dhul-Qa'da we set out from Medina in the company of Allah's Messenger (ﷺ) with the intention of performing Hajj only. When we approached Mecca, Allah's Messenger (ﷺ) ordered those who had no Hadi with them to finish their lhram after performing Tawaf of the Ka`ba and (Sa`i) and between Safa and Marwa." `Aisha added, "On the day of Nahr (slaughtering of sacrifice) beef was brought to us. I asked, 'What is this?' The reply was, 'Allah's Apostle (p.b.u.h) has slaughtered (sacrifices) on behalf of his wives.' " حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، قَالَتْ سَمِعْتُ عَائِشَةَ ـ رضى الله عنها ـ تَقُولُ خَرَجْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم لِخَمْسٍ بَقِينَ مِنْ ذِي الْقَعْدَةِ، لاَ نُرَى إِلاَّ الْحَجَّ، فَلَمَّا دَنَوْنَا مِنْ مَكَّةَ أَمَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم مَنْ لَمْ يَكُنْ مَعَهُ هَدْىٌ، إِذَا طَافَ وَسَعَى بَيْنَ الصَّفَا وَالْمَرْوَةِ أَنْ يَحِلَّ، قَالَتْ فَدُخِلَ عَلَيْنَا يَوْمَ النَّحْرِ بِلَحْمِ بَقَرٍ‏.‏ فَقُلْتُ مَا هَذَا قَالَ نَحَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ أَزْوَاجِهِ‏.‏ قَالَ يَحْيَى فَذَكَرْتُهُ لِلْقَاسِمِ، فَقَالَ أَتَتْكَ بِالْحَدِيثِ عَلَى وَجْهِهِ‏.‏
