Hadith.4945 - Zurah ibn Muhammad al-Hadrami narrated from Samaah ibn Mihran, who said: I heard Imam (as) say: "Indeed, Allah (swt), Blessed and Exalted, has promised two punishments for consuming the wealth of an orphan. One is the punishment in the Hereafter, which is the Fire, and the other is the punishment in this world, as stated by Allah (swt), the Mighty and Majestic: 'And let those fear (Allah (swt)) who, if they left behind weak offspring, would be afraid for them. So let them fear Allah (swt) and speak words of appropriate justice.' (Surah An-Nisa 4:9) This means that one should fear that Allah (swt) might deal with his own offspring as to what (wrong) he has done to these orphans."
