In this lesson we will Insha Allah learn the cases of the Diptotes i.e.,
 إِعرَابُ الأسْمَاءِ الْمَمْنُوعَةِ مِنَ الْصَّرْفِ:

• Unlike the ordinary nouns, "The Diptotes" do not take double vowel mark. Similarly, Diptotes do not take the genitive case Kasra.

• In the previous lessons we learnt the situations when a noun is in Genitive Case i.e.,

  • When it is Majroor مَجْرُوْرٌ, i.e., when it is preceded by a preposition (Lesson No. 004_section 003), and

  • When it is a possessed noun مُضَاف إِلَيْهِ of the Possessive Expression (Lesson No. 005_section 002)

• In these situations the noun takes genitive case i.e., Single Kasra if it is definite مِنَ الْبَيْتِ and double Kasra if it is indefinite فِي مَسْجِدٍ.

• However diptotes الْمَمْنُوْعِ مِنَ الْصَّرْفِ are the nouns which take fatha instead of a kasra if in genitive case. We have already learnt in the previous lesson i.e., (Lesson 20 section 4) that Diptotes are those nouns or adjectives which never take Tanwin i.e., Double Vowel Mark. So whenever a diptote noun is preceded by a preposition or is Mudhaf Ilaihi it will take a fatha instead of a kasra so if we say for example Ahmad's book i.e., كِتَابُ أَحْمَدَ

• Previously we have learnt only one situation when a noun takes the accusative case (Lesson 15 section 006) and that is:

  • When the noun is object of a verbal sentence مَفْعُوْلٌ i.e., أَكَلَ خَالِدٌ تَفَاحاً

• However since the diptote does not take Tanwin so if it is used as object of a verbal sentence it will take a single fatha instead of double vowels e.g., زَارَ طَاهِرٌ مَسَاجِدَ كَثِيْرَةً

We will learn these rules in more detail in the next sections Insha Allah
