I just realized that it wasn’t until Ya’Qub alayhissalaam’s second favourite son was taken that the trial came to a closure. Also, this is parallel to his grandfather Ibraaheem alayhissalaam who was tried with his two sons (one being Is’haaq, the father of Ya’Qub) one of whom he had to abandon and the other one kill (again, similar to the killing claimed for Yusuf and the abandonment of Benjamin in Egypt).
وَإِذِ ٱبْتَلَىٰٓ إِبْرَٰهِۦمَ رَبُّهُۥ بِكَلِمَٰتٍ فَأَتَمَّهُنَّ قَالَ إِنِّى جَاعِلُكَ لِلنَّاسِ إِمَامًا قَالَ وَمِن ذُرِّيَّتِى قَالَ لَا يَنَالُ عَهْدِى ٱلظَّٰلِمِينَ
And [mention, O Muhammad], when Abraham was tried by his Lord with commands and he fulfilled them. [Allah] said, “Indeed, I will make you a leader for the people.” [Abraham] said, “And of my descendants?” [Allah] said, “My covenant does not include the wrongdoers.”
I’m amazed that I never saw that. And my mind is always trying to find connections and patterns. But this one just popped into my mind. Allaah will reveal what He wants whenever He wants and it’s not a matter of vigilance or effort. SubhaanAllaah.
