Question: Does ‘arba‘īn ziyārah a few days before or after ‘arba‘īn have the same reward?

Answer: Ziyārah of Sayyid al-Shuhadā (peace be upon him) is recommended at any time and brings great rewards. But the reward of ziyārah at a specific time is specific to performing it at the mentioned time. Of course, there is no obstacle to performing ziyārah before or after that, hoping to achieve that special reward.
