ANSWER:

There’s no problem in this. 

However it’s best to answer the athan and recite the dua after it to be eligible for the Prophet salla Allahu Alaihi wa Sallam’s intercession on the day of judgment.

Is it a sin if we talk and eat during azaan?

I didn’t’t know that not wearing socks salah not accepted and now i came to know about it so started wearing during salah what about my previous prayers there were accepted or not? The same question about other matters of ibadah that we didn’t know something and came to know about after a long time so our previous ibadah accepted or not??

If I hear the Athan from a masjid that is ahmediya or the imam there reads fatiha too quickly or doesn’t do wudu properly, am I still obliged to go?
