It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) was drinking something, Ibn Abbas (may Allah be pleased with them both) was sitting on his right side and Sayyiduna Khalid bin Walid (may Allah be pleased with him) was on his left side. The Prophet (peace and blessings be upon him) said to him, "The right to drink is yours, but if you wish, shall I give preference to Khalid and give it to him?" He replied, "I cannot give preference to anyone over the drink left by the Prophet (peace and blessings be upon him)."
