Abu Huraira reported God’s messenger as saying, “The believer is like a plant which is continually swayed by the wind, for the believer is continually afflicted by trial; but the hypocrite is like a cedar tree which does not shake till it is cut down.”
(Bukharl and Muslim.)
Ka‘b b. Malik reported God’s messenger as saying, “The believer is like a tender plant moved by the winds, sometimes being bent down and sometimes made to stand up straight, till his appointed time comes; but the hypocrite is like the cedar standing firmly, which is unaffected by anything, till it is completely cast down.”( The idea of this tradition is that believers have many troubles during their lifetime, whereas hypocrites escape them.)
Jabir told of God’s messenger visiting Umm as-Sa’ib (Ibn 'Abd al-Barr (Isti'ab, p. 781) gives her name in this form, but says she is called by some Umm al-Musayyib) and asking, “What is the matter with you that you are trembling?” She replied, “Fever; may God not bless it.” He said, “Do not revile fever, for it removes the sins of the sons of Adam just as the bellows remove the dross of iron.”
Muslim transmitted it.
She said, “The Prophet died lying between my breast and my collarbone. I will never feel bad about anyone having a painful death after what I saw the Prophet suffer.”
