If you are in your home city, regardless in which house you live, it is not permissible for you to combine or shorten the prayer, as this is not travelling and you are back in your homeland!

I’m trying to perfect my salah. I understand the different movements and to take my time, but I don’t understand what I should visualise during salah. What image should I see when I am praying? I know the hadith of the Prophet Muhammad Peace be upon him when he said to pray as you see Allah or as Allah sees you. But what do I see? Allah as light?

Suppose an Imam finishes the second prostration of the fourth rakah in Thuhr prayer and he mistakenly starts going to the standing position; but before he can do so, the congregation reminds him (by saying ‘SubhanAllaah’); he then sits down for the tashahudd. Are the two prostration of forgetfulness a must in this case?
