Read Ruku 552 of the Quran

إِذَا جَآءَ نَصْرُ ٱللَّهِ وَٱلْفَتْحُ ﴿1﴾

When the victory of Allah has come and the conquest,

وَرَأَيْتَ ٱلنَّاسَ يَدْخُلُونَ فِى دِينِ ٱللَّهِ أَفْوَاجًۭا ﴿2﴾

And you see the people entering into the religion of Allah in multitudes,

فَسَبِّحْ بِحَمْدِ رَبِّكَ وَٱسْتَغْفِرْهُ ۚ إِنَّهُۥ كَانَ تَوَّابًۢا ﴿3﴾

Then exalt [Him] with praise of your Lord and ask forgiveness of Him. Indeed, He is ever Accepting of repentance.
