Hi cancer doesn't care about faith, religion or anything else .alot of times relatives find it harder than the person with cancer,alot of healthy people really struggle , especially what to say or do in certain circumstances .i think it's help when help neaded,or just sit and talk about anything like old times (things he likes to talk about),old memories .

Remember look after yourself as well .

Take care .

hi, I'm sorry to hear about your father and ill pray and make dua for Allah to grant him shifaa and a fast recovery and also for you to ease your worries. 
 

if it helps, my mother has been diagnosed with lung cancer, a rare form which is the aggressive type that spreads fast and she cannot get treatment such as chemo because of her other underlying liver disease. I actually understand you, I burst out crying randomly and just like you my religion is the only thing keeping me sane. 
 

I try to remember that even if she passes away and your father does, it will not be the end. In jannah perhaps you will see him, and we all have this idea that we will live for long with no hardship, test or pain but who said? Cause Allah stresses in the Quran that death will come to us, to the people you love the most, to yourself even and you can never escape it. 
I also find comfort knowing that Allah does not burden a soul more than it can bare and that this is something both you and I can get past it eventually. 
 

Jazakallah for taking your time to reply

jazakAllah for your duas

im sorry to hear about your mum. My fathers cancer was diagnosed a year ago but due to my fathers underlying conditions to there wasnt we could do chemo was a no go. My fathers conidtion has deteriated drastically over a small period of time now. 

I pray that Allah swt makes it easy on our parents becuase what my father is living right now isnt what id want any parent to go through or have to deal with. My fathers mind is still young at heart but his body no longer works with his mind if that makes sense. We have to do everything for him. 

My burdens lie with the fact i dont have anyone to talk to. I talk to my wife but i dont tell her exactly how i feel as it will burden her too we have enough to deal with then have to deal with my emotional burden.

please do keep me and my family in your duas 

may Allah swt grant you and your family sabr theough this difficult time.
