Eid Mubarak to everyone! Ramadan went by too fast but hopefully it left a positive impact on everyone to carry on with.
And well its never too late to start praying five times a day
. As for fasting without praying- it wouldve been better if you'd done it but we're no one to judge. You might still be closer to God than someone who never missed a prayer because of something/anything you ever did/do or vice versa.
Nevertheless, its best to play your cards safe and pray regularly as ordered
P.S. MAC mubarak to all as well
