la ilahe ilallah

Hadith: La ilaha illal-lah, sincerely, with the intention to win Allah's Pleasure, Allah will make the Hell-Fire forbidden for him."

Narrated ‘Utban bin Malik Al-Ansari (Radi-Allahu 'anhu):

Who was one of the men of the tribe of Bani Salim: Allah’s Apostle
(Sallallahu 'Alaihi Wa Sallam) came to me and said, “If anybody comes on
the Day of Resurrection who has said: La ilaha illal-lah, sincerely, with
the intention to win Allah’s Pleasure, Allah will make the Hell-Fire
forbidden for him.”
