Ayah-[2:43]

(And perform As-Salat and give Zakah, and bow down along with Ar-Raki`in.)

Muqatil said, "Allah's statement to the People of the Book,

(And perform As-Salah) commands them to perform the prayer behind the Prophet , (and give Zakah) commands them to pay the Zakah to the Prophet , and (and bow down along with Ar-Raki`in) commands them to bow down with those who bow down among the Ummah of Muhammad . Allah therefore commands the People of the Book to be with, and among the Ummah of Muhammad .''

In addition, Allah's statement,

(And bow down along with Ar-Raki`in) means, "And be among the believers performing the best deeds they perform, such as, and foremost, the prayer.''

Ruling:-

Many scholars said that this Ayah (2:43) is proof for the obligation of performing the prayer in congregation (for men only). I will explain this ruling in detail in Kitab Al-Ahkam Al-Kabir, Allah willing.
