Kitāb al-Muʾmin
Hadith 7676 - وعن أبي عبد الله عليه السلام قال: إن عمل المؤمن يذهب فيمهد له في الجنة كما يرسل الرجل بغلامه فيفرش له، ثم تلا: " ومن عمل صالحا فلأنفسهم يمهدون".
76. It has been reported that Abu 'Abd Allah (a.s) said: The deed of a believer goes forth and makes preparations for him in Paradise just like a man who sends ahead his servant to furnish and spread out things for him.” Then he (a.s) recited Allah's saying, “And whoever does good, they prepare (good) for their own souls. [Holy Quran 30/44]”
