Which is the most appropriate way to examine a verse ending?

Division of Surahs into Verses, Qur’anic Rhythm, and Verse Endings

• Examine only the last letter and ignore the meaning
• Treat identical rhyme consonants as obligatory at every fāṣilah
• Examine the final word’s meaning, sound, and context together
• Treat the terminal word as a standalone topic detached from context
