How do you say "to tell someone to do or not to do something" in German?
For instance,

Affirmative:
1a. He told me to meet him at Starbucks tomorrow.
1b. He told me to buy that book.
1c. He told the kid to bring him the book.

Negative:
2a. He told me to not sing.
2b. He told me to not leave work before 9 o'clock.
2c. He told me to not go to the gym after work.

How do you say "to tell someone to do or not to do something" in German?
For instance,

Affirmative:

Negative:

2b. He told me to not leave work before 9 o'clock.
2c. He told me to not go to the gym after work.

Answer

I would translate it like that:

1а. Er sagte mir, dass ich ihn morgen im Starbucks treffen soll.
1b. Er sagte mir, dass ich mir dieses Buch kaufen soll.
1c. Er sagte dem Kind, dass es ihm das Buch bringen soll.

2a. Er sagte mir, dass ich nicht singen soll.
2b. Er sagte mir, dass ich nicht vor 9 Uhr Feierabend machen soll.
2c. Er sagte mir, dass ich nach der Arbeit nicht ins Fitnessstudio gehen soll.

Maybe someone else has a better idea, I can't think about another possible translation right now.
