ALI BIN HUSAIN (ASWS), from his father HUSAIN BIN ALI (ASWS), from his father the Commander of the Believers, ALI BIN ABI TALEB (ASWS), from the MESSENGER OF ALLAH (SWT), who said:
O ALI (ASWS)! Those who love me, you, and the IMAMS (ASWS) from your sons should thank ALLAH (SWT) for the legitimacy of their birth because verily, no one loves us except those who are conceived legitimately, and no one hates us except those who are conceived illegitimately
(Ref: Amaali of Sadouq 386)
