The moon-sighting material appears in forms such as «فَأَكْمِلُوا ثَلَاثِينَ», «فَاقْدُرُوا ثَلَاثِينَ», and «فَأَكْمِلُوا عِدَّةَ شَعْبَانَ ثَلَاثِينَ». Their shared direction is clear, yet each wording remains a distinct subject of textual study.
Different routes may confirm the underlying instruction while leaving a specific additional expression open to closer verification. This is where the earlier rules on ziyadat al-thiqah and shudhudh also remain relevant.
General corroboration of a report and proof of every wording within it are not identical achievements. Keeping that distinction makes route comparison more disciplined.
