It is narrated from Sayyiduna Qais that I heard the Prophet (peace and blessings be upon him) say: Whoever drinks alcohol in this world will come on the Day of Resurrection thirsty. Beware, every intoxicating thing is alcohol, and protect yourselves from date wine.
It is narrated from Sayyiduna Wahb bin Hudhaifah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: A person has the most right to his seat. If he gets up from there and then returns, he still has the most right to it.
