Salatul Istikhara is a special prayer performed by Muslims to seek guidance from Allah in making important decisions. It is a two-rakat prayer followed by a dua (supplication) in which the person expresses their need for guidance and asks Allah to show them the best course of action.
Salatul Istikhara is considered to be a very important prayer, and it is recommended that Muslims perform it before making any major decision, such as getting married, starting a new job, or moving to a new home. It is believed that Allah will guide the person to the best decision for them, even if it is not the one they were initially hoping for.
