Ash- Shaykh al Uthaymeen, may Allaah have mercy upon him, said:
“It is a must that a person eats with three fingers; the middle finger, the index finger, and the thumb. (This is) due to that indicating good manners when one is eating and it shows humbleness. However, this is regarding the foods that three fingers are sufficient for. As for if three fingers aren’t sufficient for, such as rice, then it is okay to eat with more than three fingers.
The Reference: Sharhu Riyaadus Saaliheen,(2/595), print: al-Baseerah
Also Shaykh Albani, may Allah have mercy upon him, holds the opinion that eating with a spoon in this scenario is closer to the Sunnah instead of eating with all five fingers.
The Reference: as sisilah ad-da’eefah (3/348)
Ash- Shaykh Albani, may Allah have mercy upon him, said:
“It is strange that some feel uncomfortable to eat with a spoon believing it is opposing the Sunnah while it is (in reality) from the habits of (the people) and it is not an act of worship like riding a car and a plane and similar to that from the new means (of technology)”.
The Reference: Tawjeeh as Saaree ,page: 200,print: Ibn Rajab.
Also ash- Shaykh Muqbil, may Allah have mercy upon him, has refuted those who have lied upon him that he has written a book on the impermissibility of eating with spoons, as found in many of his tapes, whereas the Shaykh clarified that it is permissible to eat with spoons.
