Imam al-Rida (AS) was once asked the reason why a man is not allowed to remarry his divorcée numerous times unless she has married another husband first, to which he replied, ‘Verily Allah, Blessed and most High, has permitted revocable divorce twice, and said: “[Revocable] divorce may be only twice; then [let there be] either an honourable retention, or a kindly release” Quran 2:229, meaning the third time around. Because of his contracting this divorce that Allah despises so, three times over, Allah prohibits him from doing it again, so she [his divorcée is not lawful for him until she marries another husband [and he divorces her, in order that people do not plunge into divorce, taking it as a light matter, and in order that women may not be caused to suffer in the process.
الإمامُ الرِّضا (عَلَيهِ الّسَلامُ) ـ لمّا سُئلَ عن العلّةِ التي من أجلِها لا تَحِلُّ المُطَلَّقَةُ لِلعِدَّةِ لِزَوجِها حتّى تَنكِحَ زَوجاً غيرَهُ ـ: إنَّ اللّهَ تباركَ و تعالى إنّما أذِنَ في الطلاقِ مَرَّتَينِ، فقالَ عَزَّوجلَّ: «الطَّلاقُ مَرَّتانِ فَإِمْساكٌ بِمَعْروفٍ أَوْ تَسْريحٌ بِإِحْسانٍ» (البقرة / 229)؛ يَعنِي في التَّطليقَةِ الثالثةِ، ولِدُخُولِهِ فيما كَرِهَ اللّهُ عَزَّوجلَّ لَهُ مِن الطلاقِ الثالثِ حَرَّمَها اللّهُ علَيهِ، فلا تَحِلُّ لَهُ مِن بعدُ حتّى تَنكِحَ زَوجاً غَيرَهُ؛ لئلاّ يُوقِعَ الناسُ الاستِخفافَ بِالطلاقِ ولا تُضارَّ النِّساءُ.
