The Prophet (ﷺ) said, "Take refuge with Allah from the difficulties of severe calamities, from having an evil end and a bad fate and from the malicious joy of your enemies."
Sahih al-Bukhari Book 82, Hadith 22
← Previous Hadith (the freed slave of Al-Mughira bin Shu`ba) Muawiya wrote to Mughira. 'Write to me what you heard the Prophet (ﷺ) saying after his prayer.' So Al-Mughira dictated to me and said, "I heard the Prophet (ﷺ) saying after the prayer, 'None has the right to be worshipped but Allah Alone Who has no partner. O Allah! No-one can withhold what You give, and none can give what You withhold, and the fortune of a man of means is useless before You (i.e., only good deeds are of value).
