Assalaam walaikum,
The issue involves using dice. See what the scholars stated about dice. It is not chess.
So are you saying chess is ok then since it's not mentioned? I believe it's this nitpicking is what led the jews astray.
What some of the scholars have said about the prohibition of chess:
Ibn Qudaamah (may Allaah have mercy on him) said: “Chess is like dice in that it is forbidden.” (al-Mughni, 14/155),
Ibn al-Qayyim (may Allaah have mercy on him) said: “The evil consequences of chess are greater than the evil consequences of dice. Everything that points to the prohibition of dice points to the prohibition of chess even more so… This is the view of Maalik and his companions, of Abu Haneefah and his companions, of Ahmad and his companions, and the view of the majority of the Taabi’een… It is not known that any of the Sahaabah permitted it or played it. Allaah protected them from that. Everything that is attributed to any of them and says that he played it – such as Abu Hurayrah – is a fabrication and lie against the Sahaabah and is rejected by anyone who knows how the Sahaabah really were and by anyone who has sufficient knowledge to examine the reports critically. How could the best generation and the best of mankind after the Messenger of Allaah (peace and blessings of Allaah be upon him) permit playing something that prevents people from remembering Allaah and from praying, and is worse in this regard than alcohol when the player gets immersed in it, as we see in real life? How could the Lawgiver forbid dice but permit chess, which is many times worse?…” (al-Furoosiyah, 303, 305, 311).
Al-Dhahabi (may Allaah have mercy on him) said: “With regard to chess, most of the scholars say that it is haraam to play it, whether that is for money or not. If it is played for money then it is indisputably gambling. Even if it is not played for money it is still gambling and haraam, according to most of the scholars… al-Nawawi (may Allaah have mercy on him) was asked about playing chess, is it forbidden or permissible? He (may Allaah have mercy on him) replied that if it makes a person miss praying on time or he plays for money, then it is haraam, otherwise it is makrooh according to al-Shaafa’i and haraam according to others…” (al-Kabaa’ir, 89-90).
With regard to the views of the Sahaabah:
‘Abd-Allaah ibn ‘Umar (may Allaah be pleased with him) was asked about chess and he said, “It is worse than dice.”
“Dice” refers to what is used nowadays for playing backgammon, which is played on a special table. It was narrated in the ahaadeeth that it is haraam.
Abu Dawood (4938) narrated from Abu Moosa al-Ash’ari that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Whoever plays dice has disobeyed Allaah and His Messenger.” (Classed as saheeh by al-Albaani in Saheeh Abi Dawood, 4129)
Muslim (2260) narrated that the Prophet (peace and blessings of Allaah be upon him) said: “Whoever plays dice is like one who has dipped his hand in the flesh and blood of a pig.” Al-Nawawi (may Allaah have mercy on him) said: “This hadeeth is quoted as evidence by al-Shaafa’i and the majority of scholars to prove that playing dice is haraam. The phrase ‘dipped his hand in the flesh and blood of a pig’ refers to eating it, and this simile is used to show that this is haraam because it is haraam to eat that.”
