His thuhur prayer is not accepted as he was kafir at the time. As for the rest of his good deeds, Allah will restore them back if his repentance was authentic and real.

If someone commits kufr eg mokxing the hadith then offers duhr prayer and then repents to Allah for mocking the hadith will all his good deeds be written again for him and will his prayer be accepted since he prayed and then repented to Allah?

Do I have to do sijda sahw if I said sana in the second rakaat of Sunnat prayer (in Hanafi mathhab)?

A few days ago I was praying 2 Rakat Sunnah after Maghrib. Just before I said the salaam a mouse appeared which distracted me. Due to surprise I ended up looking at the mouse for a few seconds instead of the place of sajda on the prayer mat. Then I completed the prayer.
