So, you can do anything in Jannah?
Can i obtain powers and be in an Anime world and fight evil?
Like Goku for example, shoot out Kamehameha, and nice and fast combat style.
Can i jump really high and fly?
Basically, be like an Anime Character and have superpowers.
In Jannah, you can creat anything you want by Allah's leave. See Sura Al-Insan, which is reaveled for Ahlul Byt. It helps you, insha'allah.
But my sister or brother, the best reward of Jannah is being with Allah and his friends like Prophet Muhammad and his AhlulBayt.
Allah Ta'ala says,
9:72
Allah has promised the faithful, men and women, gardens with streams running in them, to remain in them [forever], and good dwellings in the Gardens of Eden.
Yet Allah’s pleasure is greater [than all these]; that is the great success.
Imam Ali says in Dua Komeyl,
My Lord! My Lord! My Lord!
Strengthen my bodily members in Your service,
And fortify my ribs in determination,
And bestow upon me earnestness in my fear of You,
And continuity in my being joined to Your service,
So that I may move easily toward You in the battlefields of the foremost,
And hurry to You among the prominent,
And desire fervently Your proximity among the fervently desirous,
And move nearer to You with the nearness of the sincere,
And fear You with the fear of those who have certitude,
And gather with the believers in Your vicinity.
It should be said that Jannah has very levels. According to Hadiths of Ahlul Bayt, the levels of Jannah is equal with the numbers of the verses of Quran. Indeed, based on the numbers of the verses of Holy Quran which we teach correctly and also do according to it in this world, we can reach the higher levels of Jannah.
Indeed, your Jannah is the manifestation of your believes and doings. There are now both Jannah and Jahannam, and you are now forming your Jannah by your believes and doing. As much as you have true believes and good doings, your Jannah is better.
The best Jannah is the Jannah of the Lord, which the one who love Allah and his frinds very much and only believe in and do what their Lord has said to them and only see Allah, can reach to it,
Holy Quran, Chapter 89,
‘O soul at peace! (27)Return to your Lord, pleased and pleasing!(28)Then enter among My servants, (29)and
enter My paradise!’ (30)
Finally, we should know,
Holy Quran, 32:17
No one knows what delights have been kept hidden for them [in the Hereafter] as a reward for what they used to do.
