MashaAllah Maddy
U r rite SD we have much more bad habits few of them u have mentioned
smoking
extravagance
chasing girls
lying(i think i have quit them)
What about weaknesses:
not having control on eyes and sight
spying on our Muslim br/Sr
not taking care of neighbors( also these ones)
not praying on time
missing sunnah prayers
not reading Quran everyday
lackin in remembrance of Allah in the morning and at night (didnt neglect them )
I m not perfect but simply trying to be a gud muslim InshaAllah,
backbiting & having doubts or suspicion about our muslim br/Sr i think both of these are in same category, 50-50 success failure ratio i hope 1 day it will be 100%
