The Prophet ﷺ said, "While a dog was going round a well and was about to die of thirst, an Israeli prostitute saw it and took off her shoe and watered it. So Allah forgave her because of that good deed."
قَالَ النَّبِيُّ ﷺ بَيْنَمَا كَلْبٌ يُطِيفُ بِرَكِيَّةٍ كَادَ يَقْتُلُهُ الْعَطَشُ إِذْ رَأَتْهُ بَغِيٌّ مِنْ بَغَايَا بَنِي إِسْرَائِيلَ فَنَزَعَتْ مُوقَهَا فَسَقَتْهُ فَغُفِرَ لَهَا بِهِ
There was a dog moving around a well whom thirst would have killed. Suddenly a prostitute from the prostitutes of Bani Isra'il happened to see it and she drew water in her shoe and made it drink, and she was pardoned because of this.
قَالَ رَسُولُ اللَّهِ ﷺ بَيْنَمَا كَلْبٌ يُطِيفُ بِرَكِيَّةٍ قَدْ كَادَ يَقْتُلُهُ الْعَطَشُ إِذْ رَأَتْهُ بَغِيٌّ مِنْ بَغَايَا بَنِي إِسْرَائِيلَ فَنَزَعَتْ مُوقَهَا فَاسْتَقَتْ لَهُ بِهِ فَسَقَتْهُ إِيَّاهُ فَغُفِرَ لَهَا بِهِ
There was a dog moving around a well whom thirst would have killed. Suddenly a prostitute from the prostitutes of Bani Isra'il happened to see it and she drew water in her shoe and made it drink, and she was pardoned because of this. (Using translation from Muslim 2245b)
قَالَ رَسُولُ اللهِ ﷺ بَيْنَا كَلْبٌ يُطِيفُ بِرَكِيَّةٍ قَدْ كَادَ يَقْتُلُهُ الْعَطَشُ إِذْ رَأَتْهُ بَغِيٌّ مِنْ بَغَايَا بَنِي إِسْرَائِيلَ فَنَزَعَتْ مُوقَهَا فَاسْتَقَتْ لَهُ فَسَقَتْهُ إِيَّاهُ فَغُفِرَ لَهَا بِهِ
"بَينمَا كَلبٌ يَطِيفُ برَكِيَّةٍ قَد كان يَقتُلُهُ العَطش إِذ رَأتْهُ بَغيٌّ مِنْ بَغَايَا بَنِي إِسرَائِيلَ فنَزَعَتْ مُوقَهَا فَأسْقَت لهُ بهِ فَسَقَتهُ فغُفِرَ لَهَا".
