Many Hadiths are narrated from the Prophet (peace be upon him) to the same effect that whoever says la ilaha illa Allah truthfully or sincerely from the bottom of their heart, will enter Jannah.

 

This Hadith teaches us that if a man’s tongue spontaneously starts uttering the basic testification of Islam: “None has the right to be worshipped but Allah” just before his death, he will undoubtedly enter Jannah.

 

However, it is not definite whether he will go to Jannah in the first phase or will be admitted to it in the second phase after undergoing a purification process.

 

This depends on the Will of Allah. Yet, admission to Jannah is subject to his thorough understanding of monotheism and its conditions, that is to say, a complete abstinence from a polytheistic conduct of life.

 

Wahb bin Munabbih was asked on this hadith and said, “admittance to Jannah needs a key, but no key can work out without teeth. The teeth of this keys are actions and righteous deeds.

 

Almighty Allah knows best.
