Sayyiduna Anas (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "There is no part of the earth upon which Allah is remembered, by prayer or by remembrance, but that from that spot down to the seventh earth it rejoices at it, and it takes pride over the parts around it. And whenever a servant stands in a barren wilderness to offer prayer, the earth adorns itself for him."
Abu Ya'la recorded it; its chain contains Musa bin Ubaydah al-Rabadhi, who is da'if (weak).
