Islamic Practices in Dzulhijjah: Tarwiyah Fasting and Nail‑Cutting Prohibition

The first ten days of Dzulhijjah are highlighted for heightened worship. The practice of fasting on the 8th of Dzulhijjah, known as the Tarwiyah fast, is encouraged by scholars despite some debate over the exact authenticity of the supporting hadith. The narration cited states that fasting on Tarwiyah expiates one year's sins, while the following day's Arafah fast expiates two years’ sins. Scholars agree that the period remains a time for increased charitable deeds, Qur'an recitation, and voluntary fasting.

In addition, a specific prohibition applies to Muslims who intend to perform the sacrificial rite (kurban) during this period. A hadith narrated by Ummu Salamah instructs believers not to cut their nails or hair once the first ten days of Dzulhijjah commence if they have made the intention to offer a sacrifice. The Indonesian Ministry of Religious Affairs confirmed the start of Dzulhijjah 1447 H on 18 May 2026 and clarified that the restriction applies only to the individual planning the kurban, not to their family members. Exceptions are allowed if cutting is unavoidable or if the person has not yet formed the intention.
