عَنْ سُلَيْمَانَ بْنِ سُلَيْمٍ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ الْمِقْدَادُ بْنُ الْأَسْوَدِ رَضِيَ اللَّهُ عَنْهُ لَا أَقُولُ فِي رَجُلٍ خَيْرًا وَلَا شَرًّا حَتَّى أَنْظُرَ مَا يُخْتَمُ لَهُ يَعْنِي بَعْدَ شَيْءٍ سَمِعْتُهُ مِنَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قِيلَ وَمَا سَمِعْتَ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ لَقَلْبُ ابْنِ آدَمَ أَشَدُّ انْقِلَابًا مِنَ الْقِدْرِ إِذَا اجْتَمَعَتْ غَلْيًا
It is narrated from Sayyiduna Miqdad bin Aswad (may Allah be pleased with him), he says: After hearing a hadith of the Noble Prophet (peace and blessings be upon him), I do not make any judgment about the goodness or evil of any person until I see on which deed his life ends. Someone asked: Which hadith have you heard? I said: I heard the Messenger of Allah (peace and blessings be upon him) say: The heart of the son of Adam turns more frequently than a pot that is boiling completely.
