It is narrated from Mansur that Ibrahim Nakha'i (may Allah have mercy on him) was asked about mixed people (Ahl al-Sadad) (where Muslims and non-Muslims are mixed), when one of them accepts Islam at the hands of a Muslim? He said: Blood money will be given on his behalf and the one who brought him to Islam will be his heir.
