I had adopted a baby boy at the age of 2 months and he is 7.5 years old and now I am in the process of making my will I do know that in accordance to Islam he is not entitled to any of my money ?
What would happen to him Allah forbid that I pass on? If I do not see for him who else will? How can I make this right?
You have done nothing wrong as yet.
Cater for him in the 1/3 portion of the will which you can give to whomsoever you want, provided not one of the automatic heirs. Create now a 'Guardian' or 'Custodian' fund for him with good knowledgable pious executors for the benefit of the adopted child.
