“Abu ‘Abd Allah (a.s.), has said that in the time of ’ Amir al-Mu’minin a child was bom with two heads and two chests on one groin. ’ Amir al-Mu’minin was asked about it; if the child receives inheritance for one or for two. He (the Imam) said, ‘The child must be allowed to sleep then called to wake up. If both wake up at the same time the share of inheritance is one share but if one wakes up and the other remains sleeping it then is two shares of inheritance.’” A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from his father from al-Qasim ibn Muhammad ibn Muhammad al-Jawhariy from Hariz ibn ‘Abd Allah a similar Hadith.
