Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) liked this 'Arajeen (a specific type of yellow wood). The Prophet (peace be upon him) used to keep it in his hand. Once, the Prophet (peace be upon him) came to the mosque. It was in his hand. The Prophet (peace be upon him) saw phlegm stuck on the wall in the direction of the qiblah in the mosque, so he scraped it off. Then the Prophet (peace be upon him) turned towards the people in the gathering and said: "Does anyone like that someone spits in front of his face?" Then the Prophet (peace be upon him) said: "When a servant stands for prayer, he faces his Lord, so he should not spit in front of him or to his right side. Rather, he should spit under his left foot. And if during prayer a person feels a strong need to spit, then he should spit on his garment and then rub it in such a way." The narrator named Sufyan demonstrated this by rubbing it with his sleeve.
