In Islamic jurisprudence, it is permissible (mubah) for men to grow their hair long. While historical records show that the Prophet Muhammad (peace and blessings be upon him) regularly kept his hair long—with lengths varying from his earlobes to his shoulders—scholars clarify that this was an expression of local cultural custom (adah) rather than a prescriptive religious ritual (sunnah) that yields specific spiritual rewards. The Prophet also shaved his head during pilgrimage, demonstrating that neither practice carries inherent religious merit.

Essential Conditions and Guidelines

If a Muslim man chooses to grow his hair long, he must adhere to several structural guidelines established in the Shariah:

  • Meticulous Grooming: Long hair must not be left unkempt or dirty. The Prophet (peace and blessings be upon him) emphasized personal hygiene and neatness, stating:

“Whoever has hair, let him take care of it.” (Sunan Abi Dawud)

  • Distinction from Women: The length and style must not cross into the territory of imitating women. The Prophet explicitly prohibited cross-gender resemblance, warning that such actions compromise a believer’s spiritual alignment.
  • Adherence to Societal Norms (‘Urf): Cultural context plays a vital role in practical application. Jurists note that if long hair is customarily associated with moral laxity, rebellion, or bad habits within a specific society, a Muslim should conform to local norms to preserve his honor and avoid attracting negative public scrutiny.

Summary

In short, while growing long hair is allowed, it is not a rewarded act of worship. A Muslim should balance personal preference with cleanliness, gender distinction, and the upright customs of his surrounding community.
