Beloved Rasoolallah (s) said I am leaving 2 things for you, the Quran and my Ahl ul Bayt. Hold on to them tightly and nothing will ever harm you and you will never go astray from the right path.
There are certain people who gave pain to Ahlullah, because of this in the Hereafter they will burn in Hell.
The burning in Hell will be the burning of all the negative characteristics. Once they are properly burned, the original pure ruh that Allah created is only left behind. If you have read the kalma, you will eventually be forgiven and be allowed to enter Jannah.
Then there are the other people who were the seekers. They yearned for Marifat. They continuously strived to defeat their weaknesses. They did mujahida. Then got blessed with Mushahida. With kashf. These people will be given a higher status than regular inmates of Jannah. This is because their real reward is Deedar e Jalwa e Haqqani. Their faces will be shining and glowing. They will only be well pleased and attentive towards their Rabb. This will be a constant naimat. In their lives on earth they dedicated themselves for this goal only. For deedar of Rabb taala. And now they will enjoy every second the deedar and tajaliyat of different Ism o Siffaat.
Allahu Akbar.
