Al-Wahid

مَنْ شَهِدَ أَنْ لا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لا شَرِيكَ لَهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ وَأَنَّ عِيسَى عَبْدُ اللَّهِ وَرَسُولُهُ... أَدْخَلَهُ اللَّهُ الْجَنَّةَ

“Whoever testifies that there is no god but Allah alone with no partner, and that Muhammad is His servant and messenger, and that Isa is the servant of Allah... Allah will admit him to Paradise.”

The testimony of Allah's oneness (Tawhid) is the key to Paradise, affirming Al-Wahid's uniqueness.

Al-Wahid negates any plurality in Allah's essence, attributes, or actions. He is One in His lordship, One in His right to be worshipped, and One in His names and attributes—none shares in any of these.

قُلْ هُوَ اللَّهُ أَحَدٌ اللَّهُ الصَّمَدُ لَمْ يَلِدْ وَلَمْ يُولَدْ وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ

Qul Huwa Allahu Ahad, Allahus-Samad, lam yalid wa lam yulad, wa lam yakun lahu kufuwan ahad

“Say: He is Allah, the One. Allah, the Eternal Refuge. He neither begets nor is born. Nor is there to Him any equivalent.”
