Sahih (Sahih Muslim)
وَحَدَّثَنَاهُ أَبُو سَعِيدٍ الأَشَجُّ، حَدَّثَنَا أَبُو أُسَامَةَ، قَالَ سَمِعْتُ الأَعْمَشَ، ذَكَرَ عَنْ عُمَارَةَ، بْنِ الْقَعْقَاعِ بِهَذَا الإِسْنَادِ وَقَالَ " كَفَافًا " .
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)
