ALLAH does justice. A person putting effort and trying to follow the commands of ALLAH is not the same as someone who ignores the commands of ALLAH.
If someone sinned in the past and they repent and Submit to ALLAH (meaning if the person becomes a Muslim) and dies upon Islam and they did good deeds, ALLAH Forgives them.
If someone is a Muslim and they did major sins or minor sins and they repent and do righteous deeds, ALLAH Forgives them.
الحَمدُ لله
ALLAH Is Perfect. ALLAH Never does injustice.
Do read the Qur’an.
Read Suratul-Insaan (Surah 76) of the Qur’aan to learn about the description of Jannah.
Jannah is a “Home of peace” which is the reward by ALLAH for the people who die as Muslimeen.
There’s no fatigue or illness in Jannah. The People of Jannah will be very beautiful physically as well as from within in terms of character.
الحَمدُ لله
Once a person enters Jannah, they will never die.
They will live eternally.
There are no arguments or fights in Jannah.
Every person of Jannah will be married. No person will be lonely or depressed.
الحَمدُ لله
Jannah is the perfect home. Jannah is beautiful.
The food of Jannah is delicious. People in Jannah will be served. They don’t need to cook.
الحَمدُ لله
Jannah is very beautiful.
الحَمدُ لله
