It goes without saying that Paradise is the greatest aim of every believer. Every Muslim strives to live in this abode of eternity and everlasting happiness. Paradise, as described by the Prophet (peace be upon him) is the infinite bliss and the highest aim and the greatest joy unequalled by any other joy or blessings. In it people see things never seen before, hear things never heard before and never thought of, since the human perception is still nothing compared to the Power of Allah.
Sheikh Muhammad Saleh Al-Munnajid, a prominent Saudi Muslim scholar and lecturer stated that: The people of Paradise will enter Paradise in the most perfect and beautiful form, in the form of their father Adam (peace and blessings be upon him), whom Allah created with His own hand and perfected his form and made his shape beautiful. Everyone who enters Paradise will be in the form of Adam. It was narrated that Abu Hurayrah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “Allah created Adam in his form, sixty cubits tall… and everyone who enters Paradise will be in the form of Adam, sixty cubits tall…” (Narrated by Al-Bukhari and Muslim)
With regard to their ages, they will all enter Paradise at the age of strength and youth, thirty-three years old. It was narrated from Mu`adh ibn Jabal (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: “The people of Paradise will enter Paradise hairless, beardless with their eyes anointed with kohl, aged thirty or thirty-three years.” (Narrated by At-Tirmidhi. Classed as sahih (authentic) by Al-Albani)
It was also narrated by Ahmad from Abu Hurayrah (may Allah be pleased with him) with the words “thirty-three years old” with no doubt. Ahmad Shakir said: “Its isnad (chain of narrators) is hasan (sound).”
