The hijrah to Allah includes abandoning what He hates and doing what He loves and accepts.
 Ibn Qayyim Al-Jawziyya
Speech remains as a slave to you, but the moment it leaves your mouth, you become its slave.
 Ibn Qayyim Al-Jawziyya
Patience is that the heart does not feel anger towards that which is destined and that the mouth does not complain.
 Ibn Qayyim Al-Jawziyya
Beware of every hour and how it passes, and only spend it in the best possible way, do not neglect yourself, but render it accustomed to the noblest and best of actions, and send to your grave that which will please you when you arrive to it.

 Ibn Qayyim Al-Jawziyya
