Equal to freeing numerous slaves

Imām Ṣādiq^(a) narrates: Those who visit Ḥusayn's grave with knowledge and understanding will be credited by Allah with the reward equivalent to freeing one thousand slaves. Furthermore, they will also earn the reward of donating one thousand horses, equipped with saddles and bridles, in the way of Allah.

Abū Saʿeed Madaʿinī recalls his conversation with Imām Ṣādiq^(a), "May I be sacrificed for you! Should I visit the grave of the Prophet's son?" The Imām^(a) responded, "Indeed, Abū Saʿeed! You must visit the grave of the Prophet's son, the most holy, the most virtuous, the purest of the pure. By making this ziyārah, Allah will reward you as if you had emancipated twenty-five slaves."
