Seeing Isham (A.S.) is a sign of sadness and bad luck. If he has a rebellious
child, it is a sign that that child is obedient.
Sometimes seeing him is interpreted as good news and joy and being safe from fears. Anyone who sees Isaac (A.S.) is provided with dignity, honor and joy, and great people and righteous servants increase in that person's generation.
Seeing him is interpreted as happiness from thought, from narrowness to spaciousness, from sin to worship, from disobedience to parents to obedience and doing good to relatives.
The Prophet.
Anyone who sees himself taking the form of Isaac or wearing his clothes becomes deathly ill but recovers later.
