It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) said to me: "O Ali, seek kindness from the merciful ones of my Ummah and you will live (in peace) under their shelter; and do not seek it from those whose hearts are hard, for the curse descends upon them. O Ali, Allah Almighty created kindness and also designated certain people for it; then He made kindness beloved to them and made doing it pleasing to them, and Allah directs those who seek kindness toward them just as He sends water toward barren land, so that through it the land and its inhabitants are brought to life. O Ali, those who do kindness in this world are the very ones who will receive kindness in the Hereafter." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Remember often the destroyer of pleasures, that is, death." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Do not acquire (a craving for building) estates and farmlands, or else you will fall into desire for the world." This hadith has a sahih (authentic) chain of narration.
