Praise be to Allah.
Allah tells us that all humans are descended from Adam and his wife. Allah, may He be exalted, says (interpretation of the meaning):
{O mankind, fear your Lord, who created you from one soul and created from it its mate and dispersed from both of them many men and women} [an-Nisa’ 4:1]
{It is He who created you from one soul and created from it its mate that he might dwell in security with her. And when he covers her, she carries a light burden and continues therein} [al-A‘raf 7:189].
This clearly indicates that Adam is the father of humanity, and that he is the one from whose progeny all humankind were created, and that all humans on earth go back to Adam and his wife.
In some hadiths, it says that Adam and his wife bore children, a male and female (twins) in each pregnancy. When they grew up, the male from one pregnancy would marry the female from the pregnancy that came before him, and the female from the second pregnancy would marry the male from the first pregnancy. That was permissible, even though they were siblings from the same father and mother, as it was a case of necessity. After their numbers increased, it was forbidden for a brother to marry his sister, even if she resulted from a different pregnancy [and was not his twin].
And Allah knows best.
