Abu Zubair says that I asked Sayyiduna Jabir (may Allah be pleased with him), "Did you see the Prophet (peace and blessings be upon him) performing prayer while riding?" He replied, "Yes." After that, a man came to the Prophet (peace and blessings be upon him) who had bought a she-camel and wanted the Prophet (peace and blessings be upon him) to supplicate for him regarding it. He tried to speak to the Prophet (peace and blessings be upon him), but the Prophet (peace and blessings be upon him) remained silent until he finished the prayer with salam, then he supplicated for him.
