عَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- أَنَّ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-قَالَ: { اَلْعُمْرَةُ إِلَى اَلْعُمْرَةِ كَفَّارَةٌ لِمَا بَيْنَهُمَا, وَالْحَجُّ اَلْمَبْرُورُ لَيْسَ لَهُ جَزَاءٌ إِلَّا اَلْجَنَّةَ } مُتَّفَقٌ عَلَيْهِ 1‏ .‏‏1 ‏- صحيح.‏ رواه البخاري ( 1773 )‏، ومسلم ( 1349 )‏، وأصح ما قيل في معنى " المبرور " هو: الذي لا يخالطه إثم.‏ قلت: وفي الحديث دلالة على استحباب تكرار العمرة خلافا لمن قال بكراهية ذلك.‏ والله أعلم.‏
Translation
Ibn ’Abbas (RAA) narrated, ‘A woman from the tribe of Juhainah came to the Prophet (ﷺ) and said, ‘My mother had vowed to perform Hajj, but she died before fulfilling her vow. Should I perform Hajj on her behalf? The Prophet (ﷺ) said

"Yes perform Hajj on her behalf. Had there been a debt on your mother, would you have paid it or not? So, pay off her debt to Allah, for He is most deserving of settlement of His debt." Related by Al-Bukhari.
