Ruling on
    illegitimate children
Question

                Can an illegitimate person enter
      Paradise if he obeys Allaah? Is there any sin on him or not?
Praise be to Allah.An illegitimate child does not bear any sin because of
    his parents’ having committed the sin of zinaa (unlawful sexual intercourse), because
    that was not of his doing. They bear their own sin, because Allaah says (interpretation of
    the meanings): 
    “… He gets reward for that (good) which he has earned, and
    he is punished for that (evil) which he has earned…” [al-Baqarah 2:286]
“… no bearer of burdens shall bear the burden of
    another…” [al-An’aam 6:164]
With regard to his ultimate destiny, the illegitimate person is like
    anyone else: if he obeys Allaah and does righteous deeds, and dies as a Muslim, then
    Paradise will be his; if he disobeys Allaah and dies as a kaafir, then he will be one of
    the people of Hell. If he mixes righteous deeds and bad deeds, and dies as a Muslim, then
    his fate is up to Allaah: if He wills, He will forgive him, if He wills, He will punish
    him, and his eventual admission to Paradise will be by the Grace and Mercy of Allaah. As
    for the hadeeth which says that an illegitimate person will not enter Paradise, this is a
    fabrication (falsely attributed to the Prophet SAWS (peace and blessings of Allaah be upon
    him)). And Allaah knows best.
