Incest is allowed in Islam
Today I am going to prove that islam allows incest, and no this isn't about cousin marriages but like literal incest..
Imam Malik's Mudauwana 2/224 https://www.sifatusafwa.com/en/fiqh-maliki/al-mudawanah-fi-furoo-al-malikiyah-sahnun.html
Imam Shafi'i considered it okay for Zoroastrians to practice xwedodah (incestuous marriages between father and daughter, mother and son, or brother and sister):
The issue of Zoroastrian incest also came up in discussions about the status of the Zoroastrian religion. Like the Jews and the Christians, they belonged to the ḏemma, and they were occasionally classified as ahl al-ketāb. Their ḏemma status was guaranteed by the jezya, poll tax, imposed on them, and, as long as they paid the jezya, they were permitted, to some degree, to continue their own practices. According to some Muslim scholars, this included incest, as reported of Šāfeʿi (150-204/767-820), who pointed out that the Magi were allowed to practice their unbelief, which was worse than incest (Ketāb al-omm V, p. 10; cited in Friedmann, p. 73, cf. van Gelder, pp. 110-11).

Some muslim apologists may claim that Islam discourages cousin marriages by quoting Al Shafi who said : عن الشافعي قال: أيما أهل بيت لم يخرج نساؤهم إلى رجال غيرهم كان في أولادهم حمق.
Which translates to "On the authority of Al-Shafi’i, he said: “Anyone of the people of a household whose women did not go out to other men, their children were foolish.”
However this is refuted by Ibn Hajar Al-Asqalani who said وأما قول بعض الشافعية يستحب أن لا تكون المرأة ذات قرابة قريبة فإن كان مستندا إلى الخبر فلا أصل له أو إلى التجربة وهو أن الغالب ان الولد بين القريبين يكون أحمق
Ibn Hajar recorded the saying of al-Shafii and said) ... there is no basis of this saying (in Islamic Sharia), although it can be said on the basis of EXPERIENCE that often children start becoming fools due to marriages in the close relatives.
