Narrated al-Bara bin 'Azib (RA):

The Prophet (ﷺ) gave a ruling regarding Hamza's daughter in favor of her maternal aunt, saying, "The maternal aunt is in the position of the mother." [al-Bukhari reported it].

وَعَنْ اَلْبَرَاءِ بْنِ عَازِبِ رَضِيَ اَللَّهُ عَنْهُمَا; { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-قَضَى فِي اِبْنَةِ حَمْزَةَ لِخَالَتِهَا, وَقَالَ: اَلْخَالَةُ بِمَنْزِلَةِ اَلْأُمِّ.‏ } أَخْرَجَهُ اَلْبُخَارِيُّ [1]‏ .‏
