The mosque and the call to prayer

The mosque is the house of Allah. We enter it with the right foot and leave it with the left, and we answer the caller to prayer.

After the adhan اللهم رب هذه الدعوة التامة والصلاة القائمة آت محمدا الوسيلة والفضيلة وابعثه مقاما محمودا الذي وعدته Allahumma rabba hadhihid-da'watit-tammah, was-salatil-qa'imah, ati Muhammadan al-wasilata wal-fadilah, wab'athhu maqaman mahmudan alladhi wa'adtah "O Allah, Lord of this perfect call and established prayer, grant Muhammad the intercession and favour, and raise him to the praised station You promised him" (Bukhari 614)

When you hear the adhan, repeat after the caller, then say this dua.
