The 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-JawziyyaHad Allah lifted the veil for his slave and shown him how He handles his affairs for him, and how Allah is more keen for the benefit of the slave than his own self, his heart would have melted out of the love for Allah and would have been torn to pieces out of thankfulness to Allah. Therefore if the pains of this world tire you, do not grieve. For it may be that Allah wishes to hear your voice by way of Dua'a. So pour out your desires in prostration and forget about it and know; that verily Allah does not forget it.
Ibn Qayyim Al-JawziyyaAnd if a person were given all of the world and what is in it, it would not fill his emptiness.
Ibn Qayyim Al-JawziyyaHappiness is attained by three things: being patient when tested, being thankful when receiving a blessing, and being repentant upon sinning.
