Hadith 1190B4

قَالَ مَالِكٌ : وَبَلَغَنِي، أَنَّ عُمَرَ بْنَ الْخَطَّابِ قَالَ : فِي الْمَرْأَةِ يُطَلِّقُهَا زَوْجُهَا وَهُوَ غَائِبٌ عَنْهَا، ثُمَّ يُرَاجِعُهَا، فَلَا يَبْلُغُهَا رَجْعَتُهُ، وَقَدْ بَلَغَهَا طَلَاقُهُ إِيَّاهَا، فَتَزَوَّجَتْ أَنَّهُ إِنْ دَخَلَ بِهَا زَوْجُهَا الْآخَرُ أَوْ لَمْ يَدْخُلْ بِهَا، فَلَا سَبِيلَ لِزَوْجِهَا الْأَوَّلِ الَّذِي كَانَ طَلَّقَهَا إِلَيْهَا. ¤
Imam Malik, may Allah have mercy on him, said: It has reached me from Sayyiduna Umar, may Allah be pleased with him, that he said: If a woman's husband travels to another country and sends her a divorce from there, then takes her back (revokes the divorce), but the woman does not know of the revocation and she marries another man, then if the first husband returns, he will have no authority over her, whether the second husband has consummated the marriage or not.
