Lump sum shortterm investment

I have a large lump sum for house deposit but unsure what is the best way to save it/invest it for 6-12 months?I would prefer to invest it, what are the aafest options for this timescale?

This is a very short time to invest in any risky asset class. You can keep it in everyday branch saver account with al rayan OR if you are non resident pakistani than Islamic Naya Pakistan certificate via roshan digital account can fetch you around 5%ish annual return
