Is it permissible to say: If you had done such-and-such, then such-and-such would have happened?

Question:
May Allah reward you, Your Eminence, father. This questioner asks: What is the ruling on saying, "If you had done such-and-such, O so-and-so, then such-and-such would have happened"?

Answer:
This is like what was mentioned earlier. If it refers to a past matter, it is blameworthy. However, if you say, "If you were to build a house for yourself" or "If you were to go out and earn a living," that is fine, as it pertains to the future and there is no harm in it.
