Verily, those who unjustly eat up the property of orphans, they eat up only a fire into their bellies, and they will be burnt in the blazing Fire!meaning, when you consume the orphan's wealth without a right, then you are only consuming fire, which will kindle in your stomach on the Day of Resurrection.It is recorded in the Two Sahihs that Abu Hurayrah said that the Messenger of Allah said,اجْتَنِبُوا السَّبْعَ الْمُوبِقَاتAvoid the seven great destructive sins.The people asked, "O Allah's Messenger! What are they?"He said, الشِّرْكُ بِاللهِ وَالسِّحْرُ وَقَتْلُ النَّفْسِ الَّتِي حَرَّمَ اللهُ إِلاَّ بِالْحَقِّ وَأَكْلُ الرِّبَا وَأَكْلُ مَالِ الْيَتِيمِ وَالتَّوَلِّي يَوْمَ الزَّحْفِ وَقَذْفُ الْمُحْصَنَاتِ الْمُوْمِنَاتِ الْغَافِلَتTo join others in worship along with Allah, magic, to kill the life which Allah has forbidden except for a just cause, to consume interest, to consume an orphan's property, to turn your back to the enemy and flee from the battlefield at the time of fighting, and to accuse chaste women who never even think of anything harmful to their chastity being good believers.
