Its fruit is lasting

Allaah says:

The example of Paradise, which the righteous have been promised, is [that] beneath it rivers flow. Its fruit is lasting, and its shade. That is the consequence for the righteous, and the consequence for the disbelievers is the Fire.

[Qur'aan 13:35]

Narrated `Abdullah bin `Abbas:

Once solar eclipse occurred during the lifetime of Allah's Messenger (sallallaahu alayhi wa sallam). He offered the eclipse prayer. His companions asked, "O Allah's Messenger (sallallaahu alayhi wa sallam)! We saw you trying to take something while standing at your place and then we saw you retreating." The Prophet (sallallaahu alayhi wa sallam) said, "I was shown Paradise and wanted to have a bunch of fruit from it. Had I taken it, you would have eaten from it as long as the world remains."

[Sahih Al-Bukhaari - Call to Prayers Chapter: To cast a look at the Imam during As-Salat (the prayer)- Hadith 748]
