Hadith 2274
´It was narrated from Abu Qilabah that Abu Umayyah Ad-Damri told him that:` he came to the Messenger of Allah from a journey and he was fasting. The Messenger of Allah said to him, "Won't you come and have meal for the breakfast?" He said: "I am fasting." The Messenger of Allah said: "Come and I will tell you about fasting. Allah, the mighty and sublime, has waived fasting and half of the prayer from the traveler."

And do not give things on the basis of Ruqba, for whoever is given something on the basis of Ruqba, it becomes part of his estate."
