I asked the Prophet Muhammad, "Tell me, what do you about my illness. I am weak because my severe ill whereas I'm rich and I have no heir except a daughter. Should I give two-thirds of my wealth?
"Prophet Muhammad also said," No ".
I said, "Half?".
Prophet Muhammad SAW said, "No".
Then the Prophet Muhammad SAW said, "A third. In fact, a third of it has been quite a lot. You better leave heir in an affluent rather than leaving them in poverty and begging it to others "(Narrated by Bukhari, Muslim, Abu Dawud, Tirmidhi, An-Nisa'i, Ibn Majah, and Damiri).
