Walaykum Asalam,

Upon reading your question, I remembered this hadith of the Messenger (peace and blessings upon him) who said:

Whoever stands with the Imam until he finishes, it is equivalent to spending the whole night in prayer. (Sunan Ibn Majah)

So, it is better for a man to pray in the masjid in congregation because the reward is greater.

We’re not sure exactly what the reason for the distraction is. Have you tried praying in another masjid, for example, to see if the problem persists? If it is possible, you may try finding another masjid with a sheikh who has beautiful, humble and soothing recitation of the Qur’an in a place that is more comfortable for you in terms of the masjid settings.

But the prayer of the man in congregation in the masjid is better than his prayer at home.

You may catch the taraweeh prayer with the Imam at the masjid, then when you go back home, you can allocate some time before fajr prayer to pray few rak’aas on your own peacefully with utmost concentration, if this makes you more connected with Allah Almighty. This way, you don’t lose on any reward and you get both the congregation and the prayer alone rewards.

I hope this helps. Please keep in touch. Salam.
