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.
