Hey guess what I still have more quick random Magi Headcanons ;D
-Cassim is the type of person to when he butters his toast doesn't wipe off the crumbs on the knife and so when he sticks the knife back in the butter it gets little toast crumbles in it
-Alibaba is a Dr Pepper addict and Hakuryuu's stuck on Monster Energy. Aladdin has tried (and failed) to get both of them to drink water
-In true PJO fashion I like to imagine that both Judar and Alibaba came back from the dark continent with a small streak of their hair greyed. Judar's ended up taking over the whole strand hanging down from behind his ear and that's why he cut them off, although it's still there, just tucked behind his ear. Alibaba's is on the opposite side in the same place, and you wouldn't be able to see it on either of them unless you looked closely
-I remember reading somewhere that it's very common for men in the middle east to hold hands completely platonically and my mind immediately shot to Alibaba just holding hands with everyone he deems as a friend. He does this with Morgiana and Aladdin frequently, he dragged Muu and Lo'lo around once doing this, holds Kouen's hand under the table during meetings for comfort, etc. But this is also why he prefers holding Judar around the waist and shoulders because that's a more romantic gesture
-Aladdin, Morgiana, and Alibaba babysit Masrur's kids and sometimes Marga. They're not very good at it but a lot of great stories come out it whenever they do
-Kouha always has a packet of fig newtons where ever he goes, he tells Kouen that they're 'protein bars' and gets away with it
-SharYams get married and they have a cat and Sharrkan pampers the hell out of this thing, everything from buying the most bougie cat food to the most elaborate scratching post. Yamraiha doesn't understand. Yams:"You're making our cat get fat" Sharrkan:"How DARE you, she is the PERFECT size >:("
-Aladdin's birthday is on December 25th
-When Sinbad got top surgery he chose not to keep his nipples but he still has them, just not attached to his chest. He threw them at Ja'far once and thoroughly traumatized him
-If Judar were to do any kind of singing in canon I would sell my SOUL to a) have him sing in mandarin and b) have his singing VA being Xiao Zhan
