The Vowel Signs of Words and Sentences
61. Does the end of an indeclinable word change if it is placed in different parts of a sentence?
Every indeclinable word that is placed in a certain part of a sentence is given the declinable state that it would have had if it was a declinable word, but this state does not change the word at all.
For example: أنا ذاهبٌ (I am a leaver.)
Or: إنّکَ صادقٌ (Verily, you are truthful.)
Or: إن صَدَقَ القَصدُ حَسُنَ العَمَلُ (If the intention is truthful the deed will be good.)
