Son's son
ابن الابن
The son of the deceased's son. He stands in his father's place when the deceased leaves no son of his own.
Their share
Each row is a family run through the engine in all four schools; the share is the group share of the son's son.

| With Daughter × 2 | 1/3 residue (ʿaṣaba) |
| With Father | 5/6 residue (ʿaṣaba) |
