Wa alaikum assalam,
Yes, you can.

Asselamu aleykum, I want to combine megrib and isha. This is the first time that I do it and I have a question about it. If I want to combine these prayers, have I to pray Isha straigh aftethe salam of the megrib prayer or can I do the adhkaar of the evening after praying megrib and than do Isha? Jizaak Allahu kheyran.

Asslam’ alaykum. Is it permissible to delay asr salah to where there’s about an hourleft until the start of maghrib? I ask this because I have severe eczemaon my face and body and I need to leave the medicine on for some hours during the day and currently only have time to put it straight after zuhr salah.

If I am praying Nafl salah and something bad recently happened to me, is it okay if after getting up from the ruku, I raise my hands and make a dua? Not as a regular habit but only because of a bad event.
