Mukhtasar Bukhari (Abridged) 1286 — Traveler gets the same reward

Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When a servant becomes ill or travels, whatever worship he used to perform while at home or in a state of health, all of that is written for him (i.e., there is no decrease in reward)."
