Majma al-Zawaid — Hadith 7135

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: Whoever among you reads the Qur'an should also acquire knowledge of the science of inheritance, for if a Bedouin meets him and says: O Muhajir, do you have knowledge of the Qur'an? He will answer: Yes. The Bedouin will say: I too can read it. Then the Bedouin will ask: O Muhajir, do you know the science of inheritance? If he answers: Yes, the Bedouin will say: This is an additional merit and something better. But if the Muhajir says: I do not know about it, the Bedouin will say: O Muhajir, what superiority do you have over me?
Al-Tabarani recorded it; its chain contains a narrator, Muhajir bin Kathir al-San'ani, and he is da'if (weak).
