Hadith 10:84
Umm al-Fadl stated that God’s Prophet said, “Being suckled once or twice does not make marriage unlawful.” In ‘A’isha’s version he said, “One or two sucks do not make marriage unlawful.” In another by Umm al-Fadl he said, “One suckling or two does not make marriage unlawful.” These are versions by Muslim.
وَعَنْ أُمِّ الْفَضْلِ قَالَتْ: أَنَّ نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَا تُحَرِّمُ الرضعة أَو الرضعتان» وَفِي رِوَايَةِ عَائِشَةَ قَالَ: «لَا تُحَرِّمُ الْمَصَّةُ والمصتان» وَفِي أُخْرَى لِأُمِّ الْفَضْلِ قَالَ: «لَا تُحَرِّمُ الإملاجة والإملاجتان» . هَذِه رِوَايَات لمُسلم
