I have not felt secure about anyone after what I heard from the Messenger of Allah ﷺ say, "The heart of the son of Adam shifts more rapidly than a cooking pot when it has reached its full boil."
ما آمن على أحد بعد الذي سمعت من رسول الله ﷺ يقول: القلب ابن آدم أسرع تقلبا من القدر إذا استجمعت غليانا.

This was narrated by Ibn Abu Asim in Sunnah (226), and by Tabarani in Kabir (20/253), both through the route of Amr bin Uthman, who said, Baqiya bin Walid narrated to us, Abdullah bin Salim narrated to us, from Abu Salama Sulayman bin Sulaym, from Abdul-Rahman bin Jubayr bin Nufayr, from his father, from Miqdad bin Aswad, who said, then he mentioned it.Its chain is hasan because of Amr bin Uthman, who is Ibn Saeed Abu Hafs Al-Himsi, about whom Abu Hatim said, "Truthful." His teacher, Baqiya bin Walid Al-Himsi, is also hasan al-hadith when he explicitly states that he heard directly, and this is such a case.It was also narrated by Bazzar (2112), and the wording here is his, and by Tabarani in Kabir (20/252), and by Hakim (2/289), all through the route of Abdullah bin Salih, who said, Muawiya bin Salih narrated to us, from Abdul-Rahman bin Jubayr bin Nufayr, from his father, from Jubayr bin Nufayr, who said, Miqdad bin Aswad came for some need, so we said, "Sit down until we find you what you need." He sat down and said, "I am amazed at people I passed by who wish for tribulations, claiming that Allah will test them through them just as He tested His Messenger ﷺ and his companions. I heard the Messenger of Allah ﷺ say, 'The truly fortunate one is he who is kept away from tribulations, the truly fortunate one is he who is kept away from tribulations' - repeating it three times - 'except one who is tried and is patient.' By Allah, I will not testify for anyone that he is among the people of Paradise until I know what he dies upon, because of a hadith I heard from the Messenger of Allah ﷺ. I heard the Messenger of Allah ﷺ say, 'The heart of the son of Adam turns over more rapidly than a boiling pot.'"Bazzar said after it, "Its chain is a hasan chain."Abdullah bin Salih is Abu Salih Al-Misri, the scribe of Layth, who has been criticized by some, but the first chain strengthens it.
