"'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.'" (Using translation from Tirmidhī 2103)
عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «اللَّهُ وَرَسُولُهُ مَوْلَى مَنْ لَا مَوْلَى لَهُ وَالْخَالُ وَارِثُ مَنْ لَا وَارِثَ لَهُ»
