أَصْدَقُ الرُّؤْيَا بِالْأَسْحَارِ
Dreams seen in the late pre-dawn hours are more truthful.
Source: Tirmidhi.
أَصْدَقُ means “more truthful” or “most truthful,” a comparative form (ism al-tafḍīl). الرُّؤْيَا means a dream. بِالْأَسْحَارِ points to late pre-dawn hours; الْأَسْحَارِ is the plural of سَحَر and does not mean the pre-dawn meal.
The wording compares dreams by time. It does not establish that every dream must predict an event. A dream by itself is not grounds for a legal judgment, an accusation, or a religious ruling.
