سَمِعْتُ أَبَا جَعْفَرٍ ( عليه السلام ) يَقُولُ كَانَ أَبُو ذَرٍّ رَحِمَهُ اللَّهُ يَقُولُ يَا مُبْتَغِيَ الْعِلْمِ إِنَّ هَذَا اللِّسَانَ مِفْتَاحُ خَيْرٍ وَ مِفْتَاحُ شَرٍّ فَاخْتِمْ عَلَى لِسَانِكَ كَمَا تَخْتِمُ عَلَى ذَهَبِكَ وَ وَرِقِكَ .
Translation
Yunus, from Musna, from Abu Baseer who said, ‘I heard Abu Ja’far<sup>asws</sup> saying: ‘Abu Zarr<sup>as</sup>, may Allah<sup>azwj</sup> have Mercy on him<sup>as</sup> was saying, ‘O seeker of the knowledge! This tongue is a key for goodness and a key for evil. Therefore, set a seal upon your tongue just as you set a seal upon your gold and your silver’.
