Happiness is attained by three things: being patient when tested, being thankful when receiving a blessing, and being repentant upon sinning.
Ibn Qayyim Al-JawziyyaSitting with the poor and less fortunate people removes the ego and pride from your heart.
Ibn Qayyim Al-JawziyyaAnd to have spent the night sleeping and awoken regretful, is better than to have spent the night standing (in prayer) and awaken impressed with oneself!
Ibn Qayyim Al-JawziyyaEvery gulp of air that goes out in a cause other than the cause of Allah will turn to sorrow and regret on the Day of Judgement.
Ibn Qayyim Al-JawziyyaThe heart, in its journey to Allah, Majestic is He, is like that of a bird; Love is its head, and fear and hope are its two wings. When the head and two wings are sound, the bird flies gracefully; if the head is severed, the bird dies; if the bird loses one of its wings, it then becomes a target for every hunter or predator.
Ibn Qayyim Al-Jawziyya
