Hadith 8:140
Narrated 'Amr bin Shu'aib on his father's authority from his grandfather:
Allah's Messenger (ﷺ) said: "No descendant of Adam may make a vow concerning something he does not possess, or set free (a slave) that he does not possess, or divorce (a woman) whom he does not possess (in marriage)." [Abu Dawud and at-Tirmidhi reported it; the latter graded it Sahih (authentic), and transmitted from al-Bukhari his statement that it is the most authentic Hadith on this subject].
وَعَنْ عَمْرِو بْنِ شُعَيْبٍ , عَنْ أَبِيهِ , عَنْ جَدِّهِ قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ لَا نَذْرَ لِابْنِ آدَمَ فِيمَا لَا يَمْلِكُ , وَلَا عِتْقِ لَهُ فِيمَا لَا يَمْلِكُ , وَلَا طَلَاقَ لَهُ فِيمَا لَا يَمْلِكُ } أَخْرَجَهُ أَبُو دَاوُدَ وَاَلتِّرْمِذِيُّ وَصَحَّحَهُ, وَنُقِلَ عَنْ اَلْبُخَارِيِّ أَنَّهُ أَصَحُّ مَا وَرَدَ فِيهِ
