What I see that the Rebbe brings as proofs "asmachtas" 1. the law that a chason is forbidden to work and 2. that he needs to fast on the day of his wedding
But I see from shulchan aruch even ezer 64 that only after the wedding he needs to not work, and from even ezer 56 end of Bais Shmuel 3 that before the wedding he needs to prepare the meal (IMHO make money to prepare the meal).
How am I supposed to understand the Rebbe? (The Rebbe brings that a chason is forbidden from work before the wedding (what is the source of this?))
Is it just good advice, and lifnim mishuras hadin (since he is already called a choson so he should not work (but I understand that he is not really called a choson yet (I heard that even in the kesuba he is not called a chossen the first time we mention his name))).
