So I already posted a question about 'low faith & struggles' which explains my situation but I was wondering something: sometimes when I get really tired of everything I pray to get my menstruation early so I don’t have to do anything all day. Is that kufr? I’m not saying that I hate praying salah but I have several mental illnesses and sometimes I’m drained so I ask for that but now I’m not sure if I’m allowed to even do it.
Alsalam alikum sister. Kufur in arabic means to disblive. So kufur is when you disblive in Allah [swt] and his prophet [pbuh] or any of there teaching.
I don't know if what you are doing is a sin and i don't think so but it is not kufur at least because you still belive from ehat i understand that you have to pray and it is one of the islamic pillers.
Hope that aswers you'r question Allah knows best.
