in each round, i.e. by kissing it with a sign
اَللّٰہُمَّ اَمَانَتِیْ اَدَّیْتُہَا وَ مِیْثَاقِیْ
Allahumma amanatii addaituha wamiisakii
O Allah! I have discharged the trust reposed with me and fulfilled my promise
تَعَاہَدْتُہٗ لِتَشْہَدَ لِیْ بِالْمُوَافَاۃِ
taahadtuhu litashaada lii bilmuwaafat
so that You can be witness of my fulfillment.
