Imām Ibn al-Qayyim said:
‘There is no [true] bliss, nor any delight, joy, or completeness for him, except in knowing Allāh, loving Him, being tranquil in the remembrance of Him, feeling delighted in drawing closer to Him and in yearning to meet Him; this being the paradise of the worldly life. Likewise, there is no delight or success for him in the Afterlife, except with his being enveloped in the Abode of Bliss in the Paradise of the next life. So there are for him two paradises, he will not enter the latter without first entering the former.
I heard Shaykh’l-Islām Ibn Taymiyyah, may Allāh sanctify his soul, saying: ‘Indeed there is a paradise in this world, whoever does not enter it will not enter the Paradise of the Afterlife.’
One of the gnostics said: ‘There are times that pass over the heart about which I say: If the people of Paradise are in the likes of this [state], then what a wonderful life they are in.
