1. Unnecessary Talking
Umar Ibn al-Khattab, may Allah be pleased with him, said: "A person who talks too much is a person who often makes mistakes, and someone who often makes mistakes, often has wrong actions. The Fire has a priority over such a frequent sinner."
2. Unrestrained Glances
It has been related that the Prophet once said words to the effect: "The glance is a poisoned arrow of shaytan. Whoever lowers his gaze for Allah, He will bestow upon him a refreshing sweetness which he will find in his heart on the day that he meets Him.".
3. Too Much Food
Al-Miqdam ibn Ma'd Yakrib said: "I heard the Messenger of Allah say: "The son of Adam fills no vessel more displeasing to Allah than his stomach. A few morsels should be enough for him to preserve his strength. If he must fill it, then he should allow a third for his food, a third for his drink and leave a third empty for easy\nbreathing."
4. Keeping Bad Company
Allah's Apostle said , "The example of a good companion (who sits with you) in comparison with a bad one, is I like that of the musk seller and the blacksmith's bellows (or furnace); from the first you would either buy musk or enjoy its good smell while the bellows\nwould either burn your clothes or your house, or you get a bad nasty smell thereof."
5. Excessive Sleeping
It is necessary for a person to have a sound sleep for good health and mind. But excessive sleeping causes an adverse impact on person. It has dire consequences on person's RIZQ and BARAKAH. Therefore there is Hadith advising Duas asking refuge from lazy and dull heart and mind.
