ANSWER:

It is recommended to say the duaa in both fard and voluntary prayers. 

When praying sunnah in tashahhud do I seek refuge with Allah from 4 things After durood Ibrahim or I stop at durood Ibrahim and do my salam.

There is a hadith regarding punishment of the grave where it describes a rock crushing the head of a person for oversleeping fard prayer and something else regarding quran. The part regarding the quran I can’t remember what the hadith says about it, does the punishment apply just for not reciting quran? Or is it only for not acting upon commands?

I saw a Hadith of Sahih Bukhari with the narration of Aisha RA where Prophet Sallallahu Alaihi Wa Sallam used to offer 2 rakah Sunnah prayer after the Asr prayer, and he never used to miss it. Now he didn’t publicize it because he wanted to keep it easy for the believers. My question is, can we offer these 2 rakah after the Asr prayer???
