There are endowments, vows, and bequests dedicated to feeding and reviving the rituals of the Ahlulbait (PBUT) specifically on the first night of Muharram, as well as in the blessed month of Ramadan and other months.

Since in some months, the confirmation of the crescent moon cannot be guaranteed before its sighting, which necessitates carrying out these actions on the night in question: •⁠⁠Is it obligatory to carry them out on the first night if they are missed? •⁠ ⁠If the guardian, trustee, or one who has made a vow wishes to act with caution on the uncertain night to ensure they are in agreement with the correct date, is there a method they should follow?

A women has a vow, which is annually distributing fruits of an amount of 250000 Iraqi dinars to the visitors of Arbaeen pilgrimage of Imam Hussein (PBUH) on the soul of lady Ruqayah.

One of the believers has made a vow that he would offer a slaughtered animal to Imam Hussein (PBUH), but he conditioned his vow that he would hold a meal inside the village in case he gets what he asked for.
