Before Starting Dua (3 times)

سُبْحَانَ اللهِ وَبِحَمْدِهِۦ عَدَدَ خَلْقِهِۦ وَرِضٰى نَفْسِهِۦ وَزِنَةَ عَرْشِهِۦ وَمِدَادَ كَلِمَاتِهِۦ

I recite the Glory and Praise of Allah equal in number to His Creation, according to His Will and Pleasure, equal in weight to that of His Throne and equal in dimensions to His Words.
