Anas ibn Mālik (may Allah be pleased with him) reported: A group from among the Prophet's Companions asked the Prophet's wives about the acts of worship that he performed in private. Some of them said: "I will not marry women." Others said: "I will not eat meat." Some others said: "I will not lie down on a bed." Their words reached the Prophet (may Allah's peace and blessings be upon him). So, he praised Allah and glorified Him and said: "What is the matter with those people who said such-and-such? Indeed, I pray and I sleep too, I fast sometimes and do not fast other times, and I marry women. Whoever turns away from my Sunnah does not belong to me."
‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) said: "O young men, those of you who can afford to should marry; it restrains the gaze and fortifies one's chastity. Those who cannot should fast; it controls the sexual desire."
Sa‘d ibn Abi Waqqās (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) forbade ‘Uthmān ibn Mazh‘ūn to be celibate. If he had given him permission we would have castrated ourselves.
‘Abdullāh ibn ‘Amr ibn al-‘Ās (may Allah be pleased with him) reported: The Messenger (may Allah's peace and blessings be upon him) said: "This world is but an enjoyment and the best of its enjoyments is a righteous woman."
Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "One may not combine in marriage a woman and her paternal aunt, or a woman and her maternal aunt."
‘Abdullāh ibn ‘Umar (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) prohibited Shighār marriage.
Shighār marriage means that a man gives his daughter in marriage to another on condition that the other gives his daughter to him in marriage without any dower being paid by either.
Iyās ibn Salamah reported that his father said: "The Messenger of Allah (may Allah’s peace and blessings be upon him) allowed temporary marriage for three nights in the year of the battle of Awtās, then he forbade it.”
