The 40th [Arbaeen (Arbayeen) or Chehlum] marks an important turning point in the movement of Karbala (Kerbala). This day, which is no less important to the day of Ashura (Aashura/Ashurah) is important for many reasons – the prime being that the Ahlul Bayt reached the land of Karbala on this day and performed the visitation to Sayyid ash-Shuhada al-Husayn (as) and the loyal family and friends who gave their life for the cause of Islam.
