Jannah (Arabic: الجنة), also spelled as Jennah, is the Arabic term for paradise, heaven, or simply "garden". The description of heaven in Islam is very vivid, more so than any other religion. However as in all the descriptions of the unseen, nothing that is described in Duniyah is a true likeness of the Akhirah.
It is recorded in a hadith Qudsi in which Allah has said,
|“||I have prepared for My slaves what no eye has seen, no ear has heard and no human heart can imagine.||„|
The different names of Jannah
The good news for Muslims in Jannah
- "Jibril said, ' . . . and with them are 70,000 who shall enter heaven without reckoning or punishment . . . they are those who do not use charms, nor seek them from others, nor draw omens, but rely upon their Lord." 
- The final part of the good news comes in another saheeh hadeeth, in which he (peace and blessings of Allaah be upon him) said: “The people of Paradise are 120 rows, of which eighty are from this ummah and the other forty from all the other nations.” 
The levels of Jannah
Paradise has one hundred levels which Allah has reserved for the mujahidin who fight in His Cause and the distance between each of the two grades is like the distance between the heavens and the earth. So when you ask Allah for something, ask for al-Firdaws which is the best and highest part of Paradise. Above it is the throne of the Most Merciful, and from it originate the rivers of Paradise". 
"The people of Paradise will look at the people dwelling in the chambers above them in the same way that people look at a brilliant star shining far away on the horizon, in the East or West, because of their superiority [in reward] over them." The people asked, "O Messenger of Allâh, are these the dwellings of the Prophets which no one else can attain?" He replied, "No by the One in Whose Hand is my soul, they are for the men who believed in Allâh, and also in His Messengers." 
The bridge to Heaven
know as as-Siraat Upon it will be lined all those that you have wronged, so that they can extract their justice. As only the pure will enter Jannah.And the trials in duniyah, death, the grave and qiyama are all stages where purification can occur.

The characteristics of men and women in Jannah
Men and women will be created from a different substance Your wives will be so beautiful that when you first see them you will look at her with mouth open for 40 years.
- If a houris where to be seen by men in the Duniyah then her light would fill the space between heaven and earth, and so will her scent, and her scarf that she wears will be worth more than the earth
- The men will be beautiful like prophet Yusuf will be 33 years of age like Eesa and they will be the same height as Adam
- Men will have the strength of a hundred men
The Rivers for the Mu'mins
The Qur'an mentions that rivers will be given to the righteous believers in paradise,
|“||And give glad tidings to those who believe and work righteousness, that their portion is Gardens, beneath which rivers flow.||„|
Water, Milk, Honey, and Wine
The Qur'an mentions that in paradise there will be rivers of different kinds. Rivers of honey, milk, wine, and water:
- "A similitude of the Garden which those who keep their duty (to Allah) are promised: Therein are rivers of water unpolluted, and rivers of milk whereof the flavour changeth not, and rivers of wine delicious to the drinkers, and rivers of clear-run honey."
"In Paradise there is a sea of honey, a sea of wine, a sea of milk and a sea of water, and the rivers flow out of these seas."
The Prophet's river
- The prophet's river, called al-Kawthar, is river found in paradise through which anyone from the Prophet's ummah can drink from. Anyone who drinks from it will never be thirsty again. The term "al-Kawthar" literally means abundance.
