قال الشيخ رحمه الله فان كانت صلاة جماعة كان الاذان والاقامة لها واجبين لا يجوز تركهما في تلك الحال
The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, said: "If the prayer is being performed in congregation, then the adhan and the iqamah are both obligatory for it, and it is not permissible to omit them in that case."
