Nor have I seen the back of a man
For fifty years, I never [once] missed the initial takbeer [upon beginning the congregational prayer], and nor have I seen the back of a man in the [congregational] prayer [since].
Whoever is not concerned with the prayer
Whoever is not concerned with [preparing for] the prayer before its time, then he has not dignified or venerated it.
