The Qur’an and Sunnah have laid great stress on the importance of the congregational prayer and its unique excellence which means that the obligatory prayer is to be offered collectively not individually unless there is a valid excuse. Almighty Allah says:
And establish prayer and give zakah and bow with those who bow [in worship and obedience]. (Al-Baqarah 2:43)
The importance of the congregational prayer in Islam is so great that Muslims were enjoined to observe it even in the battlefield where danger to life is extreme.
