Sahih al-Bukhari, Volume 9, Book 86, Hadith 90 (USC-MSA) ⓘ

Narrated Ibn Abbas: Sa'd bin 'Ubada Al-Ansari sought the verdict of Allah's Messenger regarding a vow made by his mother who had died before fulfilling it. Allah's Messenger said, "Fulfill it on her behalf." Some people said, "If the number of camels reaches twenty, then their owner has to pay four sheep as Zakat; and if their owner gives them as a gift or sells them in order to escape the payment of Zakat cunningly before the completion of a year, then he is not to pay anything, and if he slaughters them and then dies, then no Zakat is to be taken from his property."

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّهُ قَالَ اسْتَفْتَى سَعْدُ بْنُ عُبَادَةَ الأَنْصَارِيُّ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي نَذْرٍ كَانَ عَلَى أُمِّهِ، تُوُفِّيَتْ قَبْلَ أَنْ تَقْضِيَهُ، فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ اقْضِهِ عَنْهَا ‏" ‏‏.‏ وَقَالَ بَعْضُ النَّاسِ إِذَا بَلَغَتِ الإِبِلُ عِشْرِينَ، فَفِيهَا أَرْبَعُ شِيَاهٍ، فَإِنْ وَهَبَهَا قَبْلَ الْحَوْلِ أَوْ بَاعَهَا، فِرَارًا وَاحْتِيَالاً لإِسْقَاطِ الزَّكَاةِ، فَلاَ شَىْءَ عَلَيْهِ، وَكَذَلِكَ إِنْ أَتْلَفَهَا فَمَاتَ، فَلاَ شَىْءَ فِي مَالِهِ‏.‏

Narrated 'Abdullah: Nafi narrated to me that 'Abdullah said that Allah's Messenger forbade the Shighar. I asked Nafi', "What is the Shighar?" He said, "It is to marry the daughter of a man and marry one's daughter to that man (at the same time) without Mahr (in both cases); or to marry the sister of a man and marry one's own sister to that man without Mahr." Some people said, "If one, by a trick, marries on the basis of Shighar, the marriage is valid but its condition is illegal." The same scholar said regarding Al-Mut'a, "The marriage is invalid and its condition is illegal." Some others said, "The Mut'a and the Shighar are permissible but the condition is illegal."

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ عُبَيْدِ اللَّهِ، قَالَ حَدَّثَنِي نَافِعٌ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الشِّغَارِ‏.‏ قُلْتُ لِنَافِعٍ مَا الشِّغَارُ قَالَ يَنْكِحُ ابْنَةَ الرَّجُلِ وَيُنْكِحُهُ ابْنَتَهُ بِغَيْرِ صَدَاقٍ، وَيَنْكِحُ أُخْتَ الرَّجُلِ وَيُنْكِحُهُ أُخْتَهُ بِغَيْرِ صَدَاقٍ‏.‏ وَقَالَ بَعْضُ النَّاسِ إِنِ احْتَالَ حَتَّى تَزَوَّجَ عَلَى الشِّغَارِ، فَهْوَ جَائِزٌ، وَالشَّرْطُ بَاطِلٌ‏.‏ وَقَالَ فِي الْمُتْعَةِ النِّكَاحُ فَاسِدٌ، وَالشَّرْطُ بَاطِلٌ‏.‏ وَقَالَ بَعْضُهُمُ الْمُتْعَةُ وَالشِّغَارُ جَائِزٌ، وَالشَّرْطُ بَاطِلٌ‏.‏
