To ask someone to do something in Spanish, we normally use the verb pedir (to ask in this context). This is how it works if we express it in El Pretérito Imperfecto, El Pretérito Indefinido or El Pretérito Pluscuamperfecto:
De pequeña, yo siempre pedía a mis padres que me dejaran ver la tele hasta tarde.
When I was little, I always used to ask my parents to let me watch TV until late.
El ladrón me pidió que le diera todo mi dinero.
The thief asked me to give him all my money.
Susana nos había pedido que cuidásemos de su hija.
Susana has asked us to look after her daughter.
Notice how in English what is asked is expressed with an infinitive:
"The thief asked me to give him all my money"
while in Spanish we use El Imperfecto Subjuntivo, after "que":
"El ladrón me pidió que le diera/diese todo mi dinero."
The verb in El Imperfecto Subjuntivo after que will be conjugated in the person who is asked, in this case "I" (The thief asked me...)
With "pedir" you will generally find an indirect object pronoun (me, te, le, nos, os, les) in this type of sentence as one normally asks "someone" to do something, e.g "me pidió que...", "les había pedido que..." or an indirect object always using "a", e.g "Ella pedía a su hermano que...", "yo nunca pedí a Antonio que...". In English there is no need to use a preposition: "He asked Laura..." but in Spanish you do need "a": "Le pidió a Laura que...".
Here are other examples:
¿Clara os pidió que donaseis algo para su ONG?
Did Clara ask you to donate something to her NGO?
El profesor había pedido a sus padres que viniesen al colegio urgentemente.
The teacher had asked his parents to come to the school urgently.
Yo antes nunca te pedía que me ayudaras, pero ahora te necesito.
I never used to ask you to help me, but I need you now.
Remember:
See also Pedir followed by El Presente de Subjuntivo to ask someone to do something
