Al-Bukhari records a route through Muhammad b. Ziyad ← Abu Hurayrah with the instruction «فَإِنْ غُمِّيَ عَلَيْكُمْ فَأَكْمِلُوا عِدَّةَ شَعْبَانَ ثَلَاثِينَ»
If the crescent is obscured, complete the number of Sha‘ban to thirty.
The Companion is Abu Hurayrah rather than Ibn ‘Umar, so it is also a shahid. Its phrasing explicitly names Sha‘ban, while another version says to complete the count to thirty. The underlying instruction corresponds closely, making this an example of a semantic shahid.
The shared ruling and the precise phrasing of each report must be kept distinct when identifying what is being corroborated.
