Du'a to have a good business

بِسۡمِ ٱللَّهِ ٱلرَّحۡمَٰنِ ٱلرَّحِيمِ قُلۡ هُوَ ٱللَّهُ أَحَدٌ ٱللَّهُ ٱلصَّمَدُ لَمۡ يَلِدۡ وَلَمۡ يُولَدۡ وَلَمۡ يَكُن لَّهُۥ كُفُوًا أَحَدُۢ

Bismillaahir-Rahmaanir-Raheem. Qul Huwallaahu Ahad, Allaahus-Samad, lam yalid wa lam yoolad, wa lam yakul lahu kufuwan ahad

In the name of Allah, the Beneficent, the Merciful Say: He is Allah, the One Allah, the eternally Besought of all He begetteth not nor was begotten And there is none comparable unto Him

Qur'an 112:1-4 (Al-Ikhlas)
