What is the amount of the nisab (minimum threshold for zakah) that obligates the hadd (fixed Qur'anic punishment) for theft?

Question:
Is it understood from the fact that the hadiths regarding the amount of the nisab that obligates the hadd for theft mention three dirhams in one instance, and in the hadith it equals a quarter of a dinar?

Answer:
It was said, yes, this is correct. It was said that the original standard is a quarter of a dinar, and these dirhams are an appraisal of that quarter of a dinar, and a quarter of a dinar at that time was three dirhams. And it was said the opposite: the original standard is silver, the original standard is silver, which is three dirhams, because the Prophet (peace and blessings be upon him) cut off the hand of Majnun, whose value was three dirhams. The disagreement on this matter is easy; the nisab is either a quarter of a dinar or three dirhams, and one is given the choice between the two. Yes.
