If you are financially able to, you must help the youngest and the girls (if they are not married) because if one of them dies, you will inherit them! This is an obligation upon you to provide for them.

My father died almost 2 years ago, I’m the oldest one of my family and I have 2 brothers “8 and 18 years old ” and 2 sisters “16 and 21 years old ” ,Is it obligatory for me to spend on them?! Would I be sinful if I didn’t spend on them?! Notably, their pension is only 500Le because the rest of the pension goes to my step mom and half brother. Is it optional or obligatory?!
