Salam alaikum was rahmatullahi was barakatuh,
Can I use simply wall? Like, join their plans by paying to them. (https://simplywall.st/plans)
Jazak Allah khair! 
May Allah reward us all the highest level of paradise.
I have asked my question 2 days ago and why can’t I get an answer? Is this a first-come service basis fatwa forum?
Maybe if your questions are phrased in a more respectful manner, than perhaps you would get an answer?
Personally, seeing some of the questions you have posted on this forum and the manner in which you have asked these questions, if I was the admin of this forum, I would have banned you permanently by now
ok i am sorry. Jazak Allah khair. Also, can I please know where i did not say in a respectful manner? Also, how can I improve my bad behaviour? May Allah reward us all the highest level of paradise.
