Should he pray Tahiyyat al-Masjid or listen to
    the Adhaan?
Question

                I entered the mosque and the
      adhaan was being given for the prayer. Should I pray Tahiyyat al-Masjid or wait until the
      adhaan finishes?
Praise be to Allah.It is better to respond to the adhaan first,
    then pray Tahiyyat al-Masjid, so as to combine two virtuous deeds. But the issue is
    flexible.
And Allaah is the source of strength. May Allaah bless our
    Prophet Muhammad and his family and companions.
