Surah Ikhlas 10 Times:

بِسْمِ اللَّـهِ الرَّحْمَـٰنِ الرَّحِيمِ قُلْ هُوَ اللَّـهُ أَحَدٌ ﴿١﴾ اللَّـهُ الصَّمَدُ ﴿٢﴾ لَمْ يَلِدْ وَلَمْ يُولَدْ ﴿٣﴾ وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ ﴿٤﴾

Bismillaahir-Rahmaanir-Raheem. (1) Qul HuwAllahu 'Ahad. (2) Allahus-Samad. (3) Lam yalid wa lam yoolad. (4) Wa lam yakun lahu kufuwan 'ahad

In the name of Allah, the Entirely Merciful, the Especially Merciful. (1) Say, "He is Allah, [who is] One, (2) Allah, the Eternal Refuge. (3) He neither begets nor is born, (4) Nor is there to Him any equivalent." (Sura Ikhlas: 1-4) In a saheeh hadeeth, Mu'adh ibn Anas (RA) said: The Messenger of Allah (ﷺ) said: Whoever recites Surah Ikhlas 10 times, Allah will make a house for him in Paradise.
