كتاب الفرائض
Read the English translation first, with the original Arabic directly underneath.
Narrated Al-Miqdam:
I heard the Messenger of Allah (ﷺ) say: I am the heirs of Him who has none, freeing him from his liabilities, and inheriting what he possesses. A maternal uncle is the heir of Him who has none, freeing him from his liabilities, and inheriting his property.
أَنَا وَارِثُ مَنْ لاَ وَارِثَ لَهُ أَفُكُّ عَانِيَهُ وَأَرِثُ مَالَهُ وَالْخَالُ وَارِثُ مَنْ لاَ وَارِثَ لَهُ يَفُكُّ عَانِيَهُ وَيَرِثُ مَالَهُ
