Child Marriage, Waiting Period Quran 65:4
In normal circumstances, the iddat is three menstrual cycles; however, if a woman does not menstruate because of advancing age or in spite of reaching puberty, then the Quran has specified in Surah Talaq that this period would be three months. The Quranic words are وَاللَّائِي لَمْ يَحِضْنَ . In the Arabic language, the word لَمْ is used for total and strong negation. Hence the expression cannot connote those girls who have not started to menstruate; it can only connote girls who have not menstruated in spite of reaching the age.
