Whoever said that the Muhsar is not supposed to perform 'Umra or Hajj in lieu of the prevented one

وَقَالَ رَوْحٌ عَنْ شِبْلٍ، عَنِ ابْنِ أَبِي نَجِيحٍ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ إِنَّمَا الْبَدَلُ عَلَى مَنْ نَقَضَ حَجَّهُ بِالتَّلَذُّذِ، فَأَمَّا مَنْ حَبَسَهُ عُذْرٌ، أَوْ غَيْرُ ذَلِكَ فَإِنَّهُ يَحِلُّ وَلاَ يَرْجِعُ، وَإِنْ كَانَ مَعَهُ هَدْىٌ وَهُوَ مُحْصَرٌ نَحَرَهُ، إِنْ كَانَ لاَ يَسْتَطِيعُ أَنْ يَبْعَثَ بِهِ، وَإِنِ اسْتَطَاعَ أَنْ يَبْعَثَ بِهِ لَمْ يَحِلَّ، حَتَّى يَبْلُغَ الْهَدْىُ مَحِلَّهُ‏.‏ وَقَالَ مَالِكٌ وَغَيْرُهُ يَنْحَرُ هَدْيَهُ، وَيَحْلِقُ فِي أَىِّ مَوْضِعٍ كَانَ، وَلاَ قَضَاءَ عَلَيْهِ، لأَنَّ النَّبِيَّ صلى الله عليه وسلم وَأَصْحَابَهُ بِالْحُدَيْبِيَةِ نَحَرُوا وَحَلَقُوا وَحَلُّوا مِنْ كُلِّ شَىْءٍ، قَبْلَ الطَّوَافِ، وَقَبْلَ أَنْ يَصِلَ الْهَدْىُ إِلَى الْبَيْتِ، ثُمَّ لَمْ يُذْكَرْ أَنَّ النَّبِيَّ صلى الله عليه وسلم أَمَرَ أَحَدًا أَنْ يَقْضُوا شَيْئًا، وَلاَ يَعُودُوا لَهُ، وَالْحُدَيْبِيَةُ خَارِجٌ مِنَ الْحَرَمِ‏.‏Ibn Abbas رضي الله عنهما said, "The performing of Hajj is only obligatory in lieu of that Hajj which is abandoned because of personal pleasure (having sexual intercourse with his wife), and not for that which is abandoned because some genuine excuse or a similar thing (e.g., disease or lack of money), then he should finish his Ihram and there is no need for him to make up for it. And if he has a Hady with him and is prevented from performing Hajj, and he is unable to send it to its place of slaughtering, then he should slaughter it. But if he can send it, then he should not finish his Ihram till the Hady has reached its place (i.e., has been slaughtered)." Malik and others said, "He should slaughter his Hady and have his head shaved wherever he is and does not have to make up for it, because the Prophet ﷺ and his companions slaughtered the sacrifice and had their heads shaved in Al-Hudaibiya and finished their Ihram before performing the Tawaf and before the Hady reached the Ka'bah. It is not mentioned that the Prophet ﷺ ordered anybody to make up for any of the missed ceremonies or to repeat anything. And Al-Hudaibiya is outside the boundaries of the sanctuary of Makkah."
