"'Umar bin Al-Khattab sent me with a letter to Abu'Ubaidah (saying) that The Messenger of Allah ﷺ said : 'Allah and His Messenger are responsible for the one who has no patron. And the maternal uncle inherits from the one who has no heirs.'"
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ اللَّهُ وَرَسُولُهُ مَوْلَى مَنْ لاَ مَوْلَى لَهُ وَالْخَالُ وَارِثُ مَنْ لاَ وَارِثَ لَهُ
