How do I have tranquility and Khushoo in my Salah? I unfortunately always find my mind thinking about what I was doing directly before Salah, or other random things, along with wiswaas, and it makes me sad, and I wish to have a more present heart. What should I do? Barakallahu feekum Ustadh.

Ustadh AbdulAziz al-Haqqan
Come to the salah while you are not physically or mentally busy with something else. Go to the masjid early to pray a couple of rakahs and make dua. This will help you a lot in having khushu in the salah. Also contemplate the ayat recited.
