Musannaf Ibn Abi Shaybah 17638 — Those who disliked him marrying her

Abd al-Rahman al-Suda'i said: A man came to Sayyiduna Ali (may Allah be pleased with him) and said: "I have a paternal cousin whom I love and want to marry. However, I have also taken pleasure from her." Sayyiduna Ali (may Allah be pleased with him) said: "If it was something hidden, that is, penetration, then you cannot marry her; and if it was something outward, that is, a kiss and the like, then there is no harm."
