Book of Matan Jurumiyah

There are three sentence compilers: Isim, fi'il, and letters that have meaning.

(1) It can be recognized by the existence of khafadh, tanwin, and the possession of alif and lam. The khafadh letters are: مِنْ (from), إِلَى (to), عَنْ (from), عَلَى (above), فِي (on), رُبَّ (rare), بِ (with), كَ (like), لِ (for) Isim can also be recognized with qasam letters (oath), namely waw, ba and ta.
(2) The file is identified by existence: قَدْ (really / sometimes), سَ (will) ، سَوْفَ (will be) ، تَاءِ اَلتَّأْنِيثِ اَلسَّاكِنَةِ (ta ta'nits that die)
(3) The letter is something that does not fulfill the characteristics of isim and fi'il

The blessed Islam is three parts:

Khafadh, idhafah, and follow the previous one.
As for what is explained by the letter khafadh, which is what is translated by letters:
مِنْ (from), إِلَى (to), عَنْ (from), عَلَى (above), فِي (di), رُبَّ (rare), بِ (with), كَ (like), لِ (for) and with oath letters namely :

اَلْوَاوُ, الْبَاءُ, التَّاءُِ (all three mean oath: sake) and with:
مُذْ, (since) وَمُنْذُ (since)

As for what is interpreted with the idhafah, for example: غُلَامُ زَيْدٍ (Zaid's servant) and the one which is interpreted with the idhafah is the first two, which are pronounced in lam and the second is revealed by min. Then the one who is ordained in the past (for, belongs to) for example: غُلَامُ زَيْدٍ (servant (belonging to) Zaid) And who is ordained with min (of) for example: ثَوْبُ خَزٍّ (Silk (of)), بَابُ سَاجٍ (door (of) teak), خَاتَمُ حَدِيدٍ (Ring of) iron.
