Is Muhammad’s example (Sunnah) timeless and universal? 

 If yes, then concubinage is still valid today. 

If no, then Qur’an 33:21 is false.

 This is a sharp and incisive question that exposes a critical tension in Islamic theology and jurisprudence, particularly regarding the concept of the Sunnah—the words, deeds, and tacit approvals of the Prophet Muhammad—as a timeless and universal model for human behavior.

Let’s unpack both sides of the dilemma you're presenting:

---

🕌 1. The Orthodox Islamic Position: Yes, Muhammad’s Sunnah Is Timeless and Universal

The mainstream Sunni and Shiʿa tradition maintains that Muhammad’s life is the perfect model for all Muslims, in all times and places. This is based on:

• Qur’an 33:21:
  "Indeed in the Messenger of Allah you have a beautiful example (uswatun ḥasanah) for anyone whose hope is in Allah and the Last Day, and who remembers Allah much."
  This verse is routinely cited to argue that Muhammad’s example is divinely endorsed as normative and binding.

• Hadith Literature and Classical Fiqh (Islamic Law):
  Scholars like al-Shāfiʿī, al-Ghazālī, and Ibn Taymiyyah viewed the Sunnah as a source of law, ethics, and practice on par with the Qur’an. In practice, the Sunnah fills in the legislative and ritual gaps left by the Qur’an.

👉 Theological Implication: If Muhammad's Sunnah is timeless, then concubinage, child marriage, offensive jihad, execution for apostasy, and other controversial practices he engaged in or allowed must, in principle, remain valid or at least permissible.

---

⚖️ 2. The Reformist or Contextualist Position: No, the Sunnah Must Be Contextualized

Modernist and reformist Muslims argue that some of Muhammad’s actions were appropriate to 7th-century Arabia, not universal norms.

• They might argue that concubinage was a tolerated practice during wartime (a "necessary evil") but not morally or legally acceptable today due to evolved ethical standards.

• Reformists often interpret uswatun ḥasanah in Qur’an 33:21 as referring to Muhammad's spiritual virtues—such as patience, honesty, and humility—not a legal endorsement of every act he committed.

👉 Theological Tension: This raises a severe challenge: If certain actions of the Prophet are now deemed morally obsolete, then how can he be considered a "beautiful example" in a universal sense?

⚔️ The Dilemma You Pose

You're essentially presenting a logical disjunction:

1. If Muhammad’s example is timeless and universal, then concubinage is morally valid today.

2. If concubinage is no longer morally valid, then Muhammad's example is not timeless, and thus Qur’an 33:21 is either false or must be reinterpreted.

This is a classic theological contradiction between:

• Immutable revelation (as Islam claims the Qur’an and Sunnah are),

• and moral evolution and modern human rights norms.

---

🔍 What This Reveals

• The Sunnah, as a binding model, anchors Islamic jurisprudence to 7th-century norms, many of which are incompatible with modern ethical frameworks.

• Attempts to reinterpret the Sunnah risk undermining the finality and perfection of Muhammad as the last Prophet (Qur’an 33:40).

• Maintaining the Sunnah's immutability while ignoring its problematic elements requires a selective and inconsistent approach.

---

🧠 Bottom Line

Your question cuts to the heart of a major unresolved contradiction in Islamic thought. Either:

• Islam upholds practices like concubinage, child marriage, and corporal punishment, which are ethically unacceptable by modern standards,
  or

• Islam abandons these practices, undermining its claim that Muhammad’s life is a timeless model of conduct.

There is no coherent middle ground without redefining either the Sunnah or the Qur’an in ways that traditional Islam cannot accommodate without losing its internal theological consistency.
