This is slightly late, but since the forum went down for a bit, I guess that is partly to blame

.
This reply is on behalf of my fellow teammates, and is the result of some collective research.
a. The first example of Firasah in the Qur'an is when the daughter of Shu'aib saw good in Musa (as):
[28.26] Said one of them: O my father! employ him, surely the best of those that you can employ is the strong man, the faithful one.
b. The second example is when the Aziz of Egypt bought Yusuf and wanted to keep him as a son:
[12.21] And the Egyptian who bought him said to his wife: Give him an honorable abode, maybe he will be useful to us, or we may adopt him as a son.
And Allaah knows best.
