`Amrah reported that her mother died and some days remained obligatory upon her from Ramadaan, so she said to `Aa’ishah (radiyallaahu `anhaa):

Authenticated by Ibn-ut-Turkamaanee (Al-Jauhar-un-Naqee, 4/257), Al-Hilaalee (Sifat-us-Saum, chapter 16) and Al-Halabee (Ibid).

Ibn `Abbaas (radiyallaahu `anhumaa) said: “If a man becomes ill in Ramadaan and dies having refrained from fasting, then food should be given on his behalf and no making up of the days is due, and if a fast due to a vow was obligatory upon him, then his heir should fast on his behalf.”
Authenticated by Ibn Hazm (Al-Muhallaa, 7/7), Al-Albaanee (Sunan Abi Daawood, 3401; Ahkaam-ul-Janaai’z, 117 ff, f.n.) and others.
