Prophet Ya'qub was the son of Prophet Ishaq. Allah also called him "Israel," meaning "Allah's servant." He had 12 sons. The one he loved most was Yusuf — not from favoritism, but because Ya'qub saw spiritual specialness in Yusuf from a young age.
Yusuf's brothers were jealous. They threw him into a well and brought home Yusuf's shirt stained with fake blood, saying: "A wolf ate him."
Ya'qub wept. Years passed. He never stopped longing for Yusuf. His vision began to fade from continuous tears. But remarkably: Ya'qub never stopped believing Yusuf was alive. When his sons said he was overreacting, he replied: "I only complain of my grief to Allah."
Finally, after many years, Yusuf — now ruler of Egypt — was reunited with his brothers. Yusuf gave them his shirt and said: "Take this, place it on father's face, he will see again."
When Yusuf's shirt touched Ya'qub's face, his vision returned. They gathered in Egypt — a family long separated.
For children: a parent's patience is a long du'a. Allah hears, even when the answer takes time.
