To make the Heart Tender (Ar-Riqaq)
81/10. Chapter:
The Fitnah of wealth should be warded off
وَقَوْلِ اللَّهِ تَعَالَى: {إِنَّمَا أَمْوَالُكُمْ وَأَوْلاَدُكُمْ فِتْنَةٌ}.
Sahih Bukhari
وَقَالَ لَنَا أَبُو الْوَلِيدِ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، عَنْ أُبَىٍّ، قَالَ كُنَّا نَرَى هَذَا مِنَ الْقُرْآنِ حَتَّى نَزَلَتْ {أَلْهَاكُمُ التَّكَاثُرُ}
'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."
