Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) said: "There is no spot on which Allah is remembered through prayer except that it boasts over the spots around it and rejoices at the remembrance of Allah, and this joy of it reaches as far as the seven earths."
