My older brother has low-functioning autism and has become extremely violent and is in a care home. I find myself wanting Allah to take him from this world to end the suffering. Is it allowed to wish him to die if it isn't with hateful or evil intentions?
It is wrong to wish death to your brother even if he is very ill, rather you should pray to Allah (SWT) to grant him cure and recovery. The great mercy of Allah is able to cure your brother and relief him from illness. We must trust in the Mercy of Allah (SWT) in every matter even if we think it very difficult.
Wassalam.
