• Izhar halqi Correct
• Ikhfa haqiqi

• Miim Correct
• Baa

8In the phrase (man yaquulu), the silent nun meets ya. The ruling is?

• Idgham with ghunnah Correct
• Izhar halqi
• Iqlab
• Idgham without ghunnah

Explanation: The silent nun meeting ya is idgham with ghunnah because ya is one of the letters of 'yanmuu'. The nun merges into the ya with nasalization, read 'mayyaquulu'.

9Why is the silent nun in (ad-dunya) and (sinwaan) read with izhar (clear), even though it meets ya and waw which are idgham letters?

• Because they occur in one word, so it is read with absolute izhar Correct
• Because ya and waw are not idgham letters
• Because there is a shadda
• Because the nun carries a vowel

Explanation: Idgham applies only when the silent nun and the idgham letter are in two separate words. Within one word, as in 'ad-dunya' and 'sinwaan', the nun is read clearly, called absolute izhar (obligatory izhar), to keep the meaning unambiguous.

11What is the complete length of the nasalization (ghunnah) when reading ikhfa, idgham with ghunnah, and iqlab?

• One count
• Two counts Correct
• Four counts
• No fixed length

Explanation: The complete nasalization in ikhfa, idgham with ghunnah, and iqlab is held for two counts (roughly the duration of folding or opening a finger twice). This measure keeps the recitation consistent.

12In the word (an'amta), the silent nun meets the letter 'ain. The ruling is?

• Ikhfa haqiqi
