Muhaqqaq Masala

After the congregational prayer has been performed within the boundaries of the mosque, it is better to pray individually (do not perform the prayer in congregation again); this is the Zahir-e-Riwayah (manifest narration). If it is prayed in congregation with Adhan and Iqamah, it is Makruh Tahrimi (severely disliked), and praying in congregation without Adhan and Iqamah is Makruh Tanzihi (mildly disliked).
