باب مَا يُتَّقَى مِنْ فِتْنَةِ الْمَالِ‏
Sahih al-Bukhari 6440
'Ubayy said (referring to the hadith above), "We considered this as a saying from the Qur'an till the Surah (beginning with):
"The mutual rivalry (for piling up of worldly things) diverts you' (102:1) was revealed."
وَقَالَ لَنَا أَبُو الْوَلِيدِ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، عَنْ أُبَىٍّ، قَالَ كُنَّا نَرَى هَذَا مِنَ الْقُرْآنِ حَتَّى نَزَلَتْ ‏{‏أَلْهَاكُمُ التَّكَاثُرُ‏}‏
