Abu Burdah bin Abi Musa Ash'ari (may Allah be pleased with him) narrates that he and Yazid bin Abi Kabsha were together on a journey. Yazid used to fast during the journey. Sayyiduna Abu Burdah (may Allah be pleased with him) said to him: I have heard Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrate many times that the Messenger of Allah (peace and blessings be upon him) said: When a servant becomes ill or is on a journey, he is given the same reward as he used to receive for the deeds he performed while residing and in good health.
