Orphans are to have extra care, protection, advice and supervision, for the sake of the Almighty and humanity.

Muslims are to be very sensitive to the needs of the orphans and their support; to give help and assistance whenever and wherever possible.

The Almighty says in the Holy Quran:

وَيُطْعِمُونَ الطَّعَامَ عَلَى حُبِّهِ مِسْكِينًا وَيَتِيمًا وَأَسِيرًا
إِنَّمَا نُطْعِمُكُمْ لِوَجْهِ اللَّهِ لا نُرِيدُ مِنكُمْ جَزَاء وَلا شُكُورًا

          And They Feed, For The Love Of Allah, The Indigent, The Orphan, And The Captives, Saying: We Feed You For Allah's Sake: No Reward Do We Seek From You Nor Thanks.
(Surah  76:  Verse  8-9)

وَآتُواْ الْيَتَامَى أَمْوَالَهُمْ وَلاَ تَتَبَدَّلُواْ الْخَبِيثَ بِالطَّيِّبِ وَلاَ تَأْكُلُواْ أَمْوَالَهُمْ إِلَى أَمْوَالِكُمْ إِنَّهُ كَانَ حُوبًا كَبِيرًا

          And As To The Orphans, Restore Their Property (When They Reach Their Age), Don't Substitute Your Bad Things For Their Good Ones, And Devour Not Their Funds (By Mixing It Up) With Your Own;
For Of A Certainty This Is A Great Sin.
(Surah   4:  Verse 2)

أَرَأَيْتَ الَّذِي يُكَذِّبُ بِالدِّينِ    فَذَلِكَ الَّذِي يَدُعُّ الْيَتِيمَ    وَلا يَحُضُّ عَلَى طَعَامِ الْمِسْكِينِ
       
   Have You Seen The One Who Denies Religion?  It Is He Who Turns Away The Orphan And Does
          Not Urge Others To Feed The Poor.... 
(Surah  107:  Verse  1-3)

Let us take some Hadiths in this regard.  Prophet Muhammad (pbuh) says:

أنا وكافلُ اليَـتيمِ في الجَنَّةِ هكذا (وأشار بإصبعيه السبابة والوسطى)

I And The Person Who Brings Up An Orphan Will Be Like This In Heavens; And He Put His Index And Middle Finger Together.   

Imam Ali (A.S.) says in his Last Will and Testament:

My advice to you is to be conscious of Allah and steadfast in your religion.
Fear Allah in matters concerning orphans. Attend to their nutrition and do not forget their interests in the middle of yours.
