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

(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 112: 1-4) The Prophet (ﷺ) said to his companions: Can't you recite one-third of the Qur'an at night? The matter seemed difficult to them. They said: O Messenger of Allah (ﷺ), who among us can do that? Then he said: "Qul Huallahu Ahad" Surah is one third of the Qur'an.
