“Had a disbeliever (Kafir) known of all the Mercy which is in the hands of Allah, he would not lose hope of entering the Paradise (Janna), and had a believer (Mumin) known of all the punishment which is present with Allah, he would not consider himself safe from the Hellfire.” - Prophet (peace be upon him)
[Narrated by Abu Huraira (May Allah be pleased with him) and collected by Al-Bukhari, vol. 8, #476]
**Explanation: **
This Hadith conveys a profound message concerning the reality of human nature, the fact that it is only due to the heedlessness of the reality of Allah’s justice and recompense, on the part of believers that they begin to content themselves by thinking, “I have done enough for Allah, Islam, and people,” and by believing, “therefore, I am SAVED.”
Had we really known the reality of Allah’s Justice and Power, we wouldn’t ever develop such a careless and irresponsible attitude towards Islam.
On the other hand, had a sinner or disbeliever in Allah, known the magnitude of Allah’s Mercy and His willingness to forgive the worst of people, and His constant help and providence to disbelievers in this world, they would have certainly believed in God and Islam. They wouldn’t wait for ‘further proofs’ for the existence of God and His Mercy.
"This day have I perfected your religion for you, completed My favour upon you, and have chosen for you Islam as your religion. " al-Qur’an 5:3
