53. How many declinable nouns hide their vowel signs?
There are three types of declinable nouns that hide their vowel signs:

• Nouns whose last letter is an alif maqsūrah (ی).
• Nouns whose last letter is a ya' preceded by a kasrah.
54. Which declinable nouns hide all of their vowel signs?
All of the vowels are hidden:
• if the noun is a compliment to a prefixed yā' personal pronoun because it would be difficult to pronounce the vowel. For example: إنّ مَذهني إکرامي لضَیفي (Verily, my creed makes me respect my guest. )
• if the noun's last letter is an alif maqsūrah because an alif cannot take a vowel. For example:
إنّ الهُدی هُدی اللهِ (Verily guidance is Allah's guidance.)
