Thanks to an observant scholar (Mawlana Abdullah Patel), the following mistake has been found in Tasheel al-Nahw (2nd online edition). All those using the text, please correct it.
On page 24, it says,
5. إِنَّ by itself conveys emphasis. Sometimes, لَامُ التَّأْكِيْدِ can be added before the خَبَرٌ to convey even more emphasis. In this case, the خَبَرٌ must be جُمْلَةٌ فِعْلِيَّةٌ.
The last sentence (In this case, the خَبَرٌ must be جُمْلَةٌ فِعْلِيَّةٌ.) is unnecessary and should be deleted. Instead, we can add another example of khabar being jumlah ismiyyah which Malwana Abdullah pointed out, i.e.
إِنَّكَ لَرَسُوْلُ اللهِ Indeed, you are the messenger of Allah.
I have already made the necessary changes in the file given at the link in the previous post. Those who downloaded the file before today, please make note of this correction.
Finally, to all the scholars using this text: Please do let me know if you find any mistake in the text, so that the necessary correction can be made.
May Allah reward Mawlana Abdullah abundantly for pointing out the error.
Wassalam ma’a al-ikram
