Sahih Muslim
The Book Pertaining to Piety and Softening of Hearts (Kitab Al-Zuhd wa Al-Raqaiq)
Book Number: 042 / Hadith Number: 7082
'Umara b. al-Qa'qa' reported this hadith with the same chain of transmitters but instead of the word" qut" (bare subsistence) there has been used the word" Kafaf" (adequate means to meet the needs).
