If a madd letter occurs at the end of one word and the hamzah begins the next word, the rule is madd munfasil, or ja’iz munfasil. The hamzah follows the vowel only when the words are joined; identifying the word boundary is therefore essential.
«إِنَّا أَعْطَيْنَاكَ» — the alif of the first word is followed by a new word beginning with hamzah.
«فِي أَنْفُسِكُمْ» — the madd ya is followed by a hamzah at the start of the next word.
Different permitted recitational routes describe different lengths for separate madd. Once a particular reading route is adopted, its measurements should be applied consistently. If the reciter actually stops after the first word, the next word's hamzah no longer directly follows it in connected recitation, so the condition for munfasil has ceased.
