Ablution after eating what is cooked on fire
Sayyidina Abu Huraira (RA) reported that Allah's Messenger (SAW) said, ablution
becomes wajib on eating something cooked on fire, even a piece of qur'ut."
Sayyidina lbn Abbas (RA) asked Sayyidina Abu Huraira (RA), "Shall we make ablution after
consuming oil and using hot water?" So, he said, "Nephew! When you hear a hadith of
the Prophet (RAW) do not cite example for that."
