It is sunnah for the pilgrim who completed the Hajj and is returning to his hometown to say: No one is God except Allah, Who has no partner.
He is the One attributed with Dominion. He is the One Who deserves to be thanked and praised. He has Power over everything.
لا إله إلا الله وحده لا شريك له، له الملك وله الحمد وهو على كل شىء قدير
We are going back to our hometown worshipping Allah, prostrating to Him, and thanking Him.
آيبون عابدون ساجدون لربنا حامدون،
He is the One Who fulfilled His promise and gave victory to His slaves,
صدق وعده، ونصر عبده
and He alone defeated the allied blasphemers.
