Narrated ‘Utban bin Malik Al-Ansari, who was one of the men of the tribe of Bani Salim:
Allah’s Apostle came to me and said, ”If anybody comes on tne Day of Resurrection who has said: La ilaha illa Allah, sincerely, with the intention to win Allah’s Pleasure, Allah will make the Hell-Fire forbidden for him.”
[Bukhari Vol 8 book 76, Hadith 431]
