Hadith 8:35
Narrated Ibn Mas'ud (RA):
Allah's Messenger (ﷺ) cursed the man who made a woman lawful for her first husband and the one for whom she was made lawful (the men involved in Halalah). [Reported by Ahmad, an-Nasa'i and at-Tirmidhi; the latter declared it to be Sahih (authentic)].
وَعَنِ ابْنِ مَسْعُودٍ - رضى الله عنه - قَالَ : { لَعَنَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -اَلْمُحَلِّلَ وَالْمُحَلَّلَ لَهُ } رَوَاهُ أَحْمَدُ , وَالنَّسَائِيُّ , وَاَلتِّرْمِذِيُّ وَصَحَّحَهُ
