Meeting of two Non-Vowelled Letters

Meeting of two Non-Vowelled Letters *- When two non-vowelled letters meet (iltiqaa sakinayn) one of them must be dropped according to the rules of Arabic grammar either by deleting the first non-vowelled letter or by marking it with a vowel. t should be noted that this occurs only in connected speech. The letter of lengthening is dropped in connected speech only if it is followed by a conjunctive hamzah. 1/ Deleting the First: The deletion occurs in pronunciation, since the deleted letter appears in graphology in most cases. Example: (إِذَا الشَّمْسُ كُوِّرَتْ). The letter of lengthening is sometimes deleted in connected speech and at stops since it is deleted in graphology if it is followed by a conjunctive hamzah Example: the deletion of the yaa in تحى in Allah's aayah (رَبِّ أَرِنِي كَيْفَ تُحْيِ الْمَوْتَى ). 2/Vowelling the First: To prevent the meeting of two non-vowelled letters the first is marked with: fath (a), kasr (i) or dhamm (u) vowels. (To prevent the meeting of two non-vowelled letters the first is marked with kasr (i) if it occurs at the end of the word. 2-a/Kasr/i: If the first and second non-vowelled letters are conjunctive hamzahs occurring at the beginning of the second word then the first is marked with kasr (i) vowel and the conjunctive hamzah is dropped in pronunciation. Example: (قُلِ ادْعُوا اللَّهَ ) That is in cases other than those marked with a fath (a) and dhamm (u) vowels N.B. the noon resulting from nunnation is marked with a kasr (i) vowel if the nunnation is followed by a conjunctive hamzah on condition that the vowelling occurs only in the case of connected speech. Example: of this nunnation (عَادًا) is Allah's aayah (verse) (عَادًا الْأُولَى).  Likewise, the laam of the word ( الاسم ) which occurs in Surah Hujurat (سُورَةُ الْحُجُرَاتِ) because it lies between two conjunctive hamzahs that is why the laam is marked by kasr (i) vowel to prevent the meeting of two non-vowelled letters. 2-b/Fatah/a: The first non-vowelled letter is marked by a fataha (a) vowel (to prevent the meeting of two non-vowelled letters in the two following situations: First: the noon in the preposition ( من ) when it is followed by a conjunctive hamzah. Example: (Second yaa of the first person (yaa almutakalim) when it is followed by a conjunctive hamzah. Example:  اذْكُرُوا نِعْمَتِيَ الَّتِي أَنْعَمْتُ عَلَيْكُمْ) ( وَأَنَا عَلَى ذَلِكُمْ مِنَ الشَّاهِدِينَ)). 2-c/Dhamm/u: The first non-vowelled letter (saakin) takes the mark of a dhamm (u) vowel (to prevent the meeting of two non-vowelled letters (saakinayan) in the two following cases: First: the waaw of ease for plural (gam'), when it is followed by a conjunctive hamzah. Example: (فَتَمَنَّوُا الْمَوْتَ إِنْ كُنْتُمْ صَادِقِينَ). Second: the meem of plural when it is followed by a conjunctive hamzah. Example: (وَسَخَّرَ لَكُمُ اللَّيْلَ وَالنَّهَارَ).
