Silsilat al-Ahadith al-Sahihah

Sayyiduna Anas (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings of Allah be upon him) had a she-camel, which was called ‘Adhba, and no (other she-camel) could surpass it. A Bedouin came on his camel, and he surpassed it. This was very hard on the Muslims, and they began to say that ‘Adhba has been left behind. The Messenger of Allah (peace and blessings of Allah be upon him) said: “Indeed, it is a right upon Allah that whatever He raises in this world, He also lowers it.”
