Article sectionWhat Are the Islamic Signs of Puberty?
Scholars generally agree that the discharge of semen is a sign for both males and females and that menstruation is a sign specific to females. There is juristic disagreement over some details concerning the growth of hair and age. This article follows the stronger view indicated by the hadiths, according to which the practical signs of puberty are:
- The discharge of semen with desire while awake, or finding it after sleep.
- The growth of coarse hair around the private area, not merely fine, light hair. According to the stronger view, this is a recognized sign.
- Completing fifteen lunar years when no sign has appeared earlier. This is the view of the majority of scholars and is supported by the hadith of Ibn Umar, may Allah be pleased with them both.
- Menstruation, which is a sign specific to a girl.
As soon as one of these recognized signs appears, the boy or girl has reached puberty and becomes religiously accountable, even if the other signs have not appeared.
The First Sign: Discharge of Semen
The discharge of semen from a male or female with desire while awake, or finding it after sleep, is a sign of puberty. The ruling is connected to the discharge itself, not merely to seeing a dream. According to the stronger view, if it is discharged while awake because of illness, cold, or something similar without desire, puberty is not established by it.
Umm Sulaym, may Allah be pleased with her, said:
"O Messenger of Allah, Allah is not shy of the truth. Must a woman perform ghusl if she has a wet dream?" The Messenger of Allah, peace and blessings be upon him, replied: "Yes, if she sees the fluid."
Agreed upon: narrated by al-Bukhari (282) and Muslim (313).
Someone who experiences in sleep what a sleeping person may experience but finds no trace of semen does not have to perform ghusl merely because of the dream. Someone who finds semen after sleeping must perform ghusl even if no dream is remembered.
Parents should not ask a son or daughter to describe intimate details. It is sufficient to teach them before this stage that finding semen after sleep, or its discharge with desire while awake, requires ghusl and establishes puberty, and to give them a safe and respectful way to ask questions.
The Second Sign: Growth of Coarse Hair Around the Private Area
The growth of coarse pubic hair around the private area is a recognized sign of puberty according to a group of scholars and is supported by the Sunnah. Scholars cited the hadith of Atiyyah al-Qurazi, may Allah be pleased with him, as evidence for considering this growth. It was narrated by Abu Dawud, al-Tirmidhi, and al-Nasai, and authenticated by al-Tirmidhi and al-Albani. Fine, light hair found on children is not a sign. Hair on the leg, arm, or underarm, and the appearance of facial hair, are not by themselves decisive Islamic signs.
This is a private sign that parents may not search for through exposure or inspection. The boy and girl should be taught the ruling. If the sign appears, they may inform a parent or another trusted person when needed, without violating modesty or privacy.
The Third Sign: Completing Fifteen Lunar Years
If no wet dream or discharge of semen has occurred, coarse hair has not grown, and a girl has not menstruated, then completing fifteen lunar years is a sign of puberty according to the majority of scholars.
Abdullah ibn Umar, may Allah be pleased with them both, said:
"The Messenger of Allah, peace and blessings be upon him, presented me for battle on the day of Uhud when I was fourteen years old, and he did not permit me. He presented me on the day of the Trench when I was fifteen years old, and he permitted me."
Agreed upon: narrated by al-Bukhari (2664) and Muslim (1868).
Nafi, may Allah have mercy on him, said: I came to Umar ibn Abd al-Aziz while he was the caliph and narrated this hadith to him. He said: "This is indeed a boundary between the young and the adult."
The year intended here is the Hijri lunar year, which is shorter than the solar year. Fifteen lunar years therefore equal approximately fourteen and a half solar years. It is not correct to rely on age according to the Gregorian calendar without noticing this difference.
Jurists differed concerning the age used when no other signs appear. However, considering the completion of fifteen lunar years is a strong view supported by the Sunnah and is most suitable for general application. Someone with a complicated prior situation or an uncertain birth date should ask a trustworthy scholar how to estimate it.
The Fourth Sign for a Girl: Menstruation
If a girl sees genuine menstrual blood, she has reached puberty even if she is younger than fifteen. Her cycle does not have to become regular from the first occurrence; it may come earlier or later and may change at the beginning.
Not every instance of bleeding seen by a young girl is necessarily menstruation. It may result from illness, injury, or a hormonal disorder. If bleeding appears at a very early age, is accompanied by severe pain or heavy bleeding, or continues in an unusual manner, a pediatrician or relevant medical specialist should be consulted. A trustworthy female or male scholar should also be asked about the Islamic ruling according to the actual nature of the blood.
A family must not meet a girl’s first menstruation with blame or fear. Rather, they should explain that it is something Allah has decreed for the daughters of Adam and teach her the rulings of ghusl, prayer, fasting, and covering in an atmosphere of compassion and privacy.
Bodily Changes That Are Not Decisive Islamic Signs by Themselves
Some changes may medically indicate that puberty is approaching, but they do not by themselves establish religious accountability unless accompanied by a recognized sign. These include:
- A change in the voice.
- The appearance of acne.
- An increase in height or a change in body shape.
- Breast development in a girl.
- The appearance of underarm or facial hair.
- Increased sweating or a change in body odor.
- Mood changes or a desire for independence.
These changes alert parents to the need to complete instruction and preparation, but none alone establishes that the child has become accountable.
