Narrated Thawban:

"When (the following) was revealed: And those who hoard up gold and silver... (9:34)" He said: "We were with the Messenger of Allah ﷺ during one of his journeys, so some of his Companions said: (This) has been revealed about gold and silver, if we knew which wealth was better then we would use it. So he ﷺ said: 'The most virtuous of it is a remembering tongue, a grateful heart, and a believing wife that helps him with his faith.'"

حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، عَنْ إِسْرَائِيلَ، عَنْ مَنْصُورٍ، عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ، عَنْ ثَوْبَانَ، قَالَ لَمَّا نَزَلَتْ : ( وَالَّذِينَ يَكْنِزُونَ الذَّهَبَ وَالْفِضَّةَ ) قَالَ كُنَّا مَعَ النَّبِيِّ ﷺ فِي بَعْضِ أَسْفَارِهِ فَقَالَ بَعْضُ أَصْحَابِهِ أُنْزِلَ فِي الذَّهَبِ وَالْفِضَّةِ مَا أُنْزِلَ . لَوْ عَلِمْنَا أَىُّ الْمَالِ خَيْرٌ فَنَتَّخِذَهُ فَقَالَ " أَفْضَلُهُ لِسَانٌ ذَاكِرٌ وَقَلْبٌ شَاكِرٌ وَزَوْجَةٌ مُؤْمِنَةٌ تُعِينُهُ عَلَى إِيمَانِهِ " . قَالَ هَذَا حَدِيثٌ حَسَنٌ . سَأَلْتُ مُحَمَّدَ بْنَ إِسْمَاعِيلَ فَقُلْتَ لَهُ سَالِمُ بْنُ أَبِي الْجَعْدِ سَمِعَ مِنْ ثَوْبَانَ فَقَالَ لاَ . فَقُلْتُ لَهُ مِمَّنْ سَمِعَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ قَالَ سَمِعَ مِنْ جَابِرِ بْنِ عَبْدِ اللَّهِ وَأَنَسِ بْنِ مَالِكٍ وَذَكَرَ غَيْرَ وَاحِدٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ .
