As regards inserting a finger or a sex toy and the like in a male’s anus in order to stimulate him, doing so is not permissible, since it goes against the pure nature on which Allah has created humans and leads to homosexuality which is decisively forbidden. A male may stimulate himself for sexual intercourse by kissing, touching, necking and other foreplay acts. Yet, inserting something in the male anus is not permissible because is included in homosexual acts which is not permissible. A Muslim must forsake these acts and seek the help of Allah by supplication and reciting the Qur’an in order to get you on the right way.
Regarding sucking a wife’s breast, Sheikh Yusuf Al-Qaradawi, states:
“During the life-time of the Prophet’s Companions (may Allah be pleased with them all) it happened that one of the Companions was making love with his wife, and in the course of love-making he (the Companion) sucked her breasts to the extent that some of the milk reached his stomach. Following that, the Companion went to Abu Musa Al-Ash`ari (may Allah be pleased with him) and asked him about the ruling. Replying the man, Abu-Musa Al-Ash`ari said that the man’s wife had become forbidden for him. (i.e., like his mother)
After that, the man went to ask `Abdullah Ibn Mas`ud (may Allah be pleased with him) about the same ruling and Ibn Mas`ud stated that there was nothing wrong with what happened. Ibn Mas`ud backed his argument by citing the Prophetic hadith, which clearly states that suckling is confined only to the two earlier years of a child. Ibn Mas`ud cited this Qur’anic verse: ‘Mothers shall suckle their children for two whole years; (that is) for those who wish to complete the suckling…’ (Al-Baqarah: 233)
the apparent meaning of the aforementioned verse is that the suckling, which may act as a cause of prohibition, is confined to the suckling during the first two years. After the elapse of the first two years, suckling is no longer a cause of prohi
In conclusion, sucking the wife’s breast, as far as Islam is concerned, does not render her unlawful for the husband.”
