There is no single "perfect age" in Islam. Islamic teachings do not prescribe a specific ideal age for marriage or any other life stage. The appropriate age for major life events, such as marriage, depends on various individual, social, and cultural factors.
Marriage in Islam: No Prescribed Age
According to Islamic teachings, there is no set "best age to marry." [07-Feb-2015 Reference] While some Muslims may cite the mid-20s as an ideal time [Reddit r/islam, May 1, 2023], this is a personal opinion, not a religious requirement. The decision to marry should be made when an individual is mature enough to handle the responsibilities of marriage, in accordance with their respective country's legal requirements. Factors such as financial stability and emotional maturity are often considered [Reddit r/islam, Aug 27, 2023]. Consultation with religious leaders (Imams) is often recommended for guidance.

This perspective contrasts with the discussions around the age of Prophet Muhammad's marriage to Aisha, which remains a point of ongoing scholarly debate [Yaqeen Institute, Oct 3, 2018].
Other Life Stages: Individual and Contextual
Similarly, Islam doesn't specify ideal ages for other life stages. The focus is on personal development, fulfilling responsibilities, and living a righteous life according to Islamic principles, regardless of age. For example, while circumcision is recommended in Islam at an early age, [London Circumcision Centre, Apr 5, 2019], the specific age is not strictly defined. This is true for other aspects of life as well. The concept of a "perfect age" is not a central tenet of Islamic faith.
Age in the Afterlife: A Different Perspective
The question of age in heaven ("Jannah") is addressed differently. Islamic beliefs suggest that the concept of age, as we understand it in this world, doesn't apply in the afterlife [Reddit r/islam, Dec 26, 2021].
