Abu Dharr (may Allah be pleased with him) narrates from the Prophet (peace and blessings of Allah be upon him), he said: "Renunciation of the world (zuhd) does not mean making the lawful unlawful and wasting wealth, but true renunciation of the world is that what is in your hand is not more trustworthy to you than what is in Allah’s hand, and that when you are afflicted with a calamity, you do not wish that it had not happened to you, hoping for the reward of that calamity." (Tirmidhi, Ibn Majah) Imam Tirmidhi said: This hadith is gharib, and the narrator Amr bin Waqid is munkar al-hadith. Its chain is weak. Narrated by Tirmidhi and Ibn Majah.
