Janazah & Burial of an illegitimate child
Is it permissible or not to perform the Janazah Salaah of one who is born out of adultery, and to bury him in the cemetery of the Muslims?
The mother of the child of adultery is an unbeliever (kafirah) and his father is a Muslim.
If he is a Muslim, then to perform his Janazah Namaz is Fard, and it is indeed permissible to bury him in the cemetery of the Muslims, even though his mother or father, or both of them are unbelievers.
The Hadith pertaining to this has already been mentioned in the answer to The Janazah Namaz a benamazi, and in this case, it is even more important to perform his Janazah Salaah, because there is no fault of his, that he is the child of adultery.
