Narrated Duba'ah daughter of az-Zubayr ibn AbdulMuttalib:

Al-Miqdad went to Baqi' al-Khabkhabah for a certain need. He found a mouse taking out a dinar from a hole. It then continued to take out dinars one by one until it took out seventeen dinars. It then took out a red purse containing a dinar. There were thus eighteen dinars. He took them to the Prophet (ﷺ), informed him and said to him: Take its sadaqah. The Prophet (ﷺ) asked him: Did you extend your hand toward the hole? He replied: No. The Messenger of Allah (ﷺ) then said: May Allah bless you in it.

حَدَّثَنَا جَعْفَرُ بْنُ مُسَافِرٍ، حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ، حَدَّثَنَا الزَّمْعِيُّ، عَنْ عَمَّتِهِ، قُرَيْبَةَ بِنْتِ عَبْدِ اللَّهِ بْنِ وَهْبٍ عَنْ أُمِّهَا، كَرِيمَةَ بِنْتِ الْمِقْدَادِ عَنْ ضُبَاعَةَ بِنْتِ الزُّبَيْرِ بْنِ عَبْدِ الْمُطَّلِبِ بْنِ هَاشِمٍ، أَنَّهَا أَخْبَرَتْهَا قَالَتْ، ذَهَبَ الْمِقْدَادُ لِحَاجَتِهِ بِبَقِيعِ الْخَبْخَبَةِ فَإِذَا جُرَذٌ يُخْرِجُ مِنْ جُحْرٍ دِينَارًا ثُمَّ لَمْ يَزَلْ يُخْرِجُ دِينَارًا دِينَارًا حَتَّى أَخْرَجَ سَبْعَةَ عَشَرَ دِينَارًا ثُمَّ أَخْرَجَ خِرْقَةً حَمْرَاءَ - يَعْنِي فِيهَا دِينَارٌ - فَكَانَتْ ثَمَانِيَةَ عَشَرَ دِينَارًا فَذَهَبَ بِهَا إِلَى النَّبِيِّ صلى الله عليه وسلم فَأَخْبَرَهُ وَقَالَ لَهُ خُذْ صَدَقَتَهَا ‏.‏ فَقَالَ لَهُ صلى الله عليه وسلم ‏"‏ هَلْ هَوَيْتَ إِلَى الْجُحْرِ ‏"‏ ‏.‏ قَالَ لاَ ‏.‏ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ بَارَكَ اللَّهُ لَكَ فِيهَا ‏"‏ ‏.‏
