Save yourself from jealousy because the deeds of jealous person do not reach even upto sixth heaven. They are thrown back at his face. He is disappointed in both the worlds – In this world because of jealousy and in the next world because of punishment.
To know the bad result of jealousy, it is suffice to say that shaitan was dishonoured because of jealousy. The brothers of Hazrat Yusuf (a.s.) faced insult and dishonour because of jealousy.
(Majmaul Bayan – 5, p. 211)
One who is jealous cannot become a leader.
Jealousy eats faith as fire eats wood.
Beware, don’t criticize acts of Allah. Don’t say ‘Today it is too hot or cold’ or say ‘how I wish I was rich’, ‘how I wish I was cured of the disease’ or ‘how I wish I was given a son instead of a daughter’. Saying all these things are like criticizing Allah. These are included in ‘Hidden Shirk’.
Son, never ask for things which harms you, e.g. God, give me death or take away my life. All these are against the will of Allah.
Beware, don’t sin because of someone’s threat, because there is salvation and ‘Aafiyat’ in desisting from sin. Didn’t you see that when Hazrat Yusuf (a.s.) did not fall to the temptations of Zulekha, Allah rewarded him with kingdom of Egypt.
