Surah An-Nasr (Victory:110)
In the name of Allah, The Beneficent, The Merciful.
When the victory granted by Allah and the conquest come;
And you see people embracing the religion of Allah in large numbers;
Then celebrate the praises of your Lord, and seek His forgiveness.
He is ever disposed to mercy.
