Sunan Abi Dawud, Hadith 1467 ⓘ
Waki' and Ibn 'Uyainah said (explaining the meaning of taghanni): This means that the Qur'an makes a man neglect all other things, and be content with it.
حَدَّثَنَا مُحَمَّدُ بْنُ سُلَيْمَانَ الأَنْبَارِيُّ، قَالَ قَالَ وَكِيعٌ وَابْنُ عُيَيْنَةَ يَعْنِي يَسْتَغْنِي بِهِ .
