You must not learn from him; even if it is for free!
From what I understand from your lines, he is on some drugs and you must stay away from him and not test yourself against the commands of Allah!

I mentioned this to u before not sure if u remember or not but some guy offered to teach me arabic but he skips magrib and prays it altogether with isha..u told me find someone else to teach me then one other guy was another guy on skype but he wants me to pay i don’t want to pay also this guy that i told u about that doesn’t pray maghrib on time seems to be my only option at least he doesnt charge not only that but im not worried about his ways rubbing off on me im going to show him strong that i could live a happy life without chewing qat and i just came out of missing prayers and started praying on time for everything n i don’t anyone could shake me last but not least i think there’s a slight chance he may benefit from me so please tell me wat i should do sheikh
