Hadith 124

Bulugh al-Maram

Book 8: Marriage
وَفِي رِوَايَةٍ أُخْرَى : قَالَ عَبْدُ اَللَّهِ بْنُ عُمَرَ : { فَرَدَّهَا عَلَيَّ , وَلَمْ يَرَهَا شَيْئًا , وَقَالَ : " إِذَا طَهُرَتْ فَلْيُطَلِّقْ أَوْ لِيُمْسِكْ } 1‏ .‏
Another narration [of Muslim] has:

"Abdullah bin 'Umar (RA) said: 'So he returned her to me and did not regarded it as anything, and said: When she is purified, either divorce her or keep her.'"
