From the perfection of Allah's ihsan is that He allows His slave to taste the bitterness of the break before the sweetness of the mend. So He does not break his believing slave, except to mend him. And He does not withhold from him, except to give him. And He does not test him (with hardship), except to cure him.
Ibn Qayyim Al-JawziyyaWhoever mocks his brother for a sin they repented from will not die till he himself falls into the same sin.
Ibn Qayyim Al-JawziyyaThere are no means of attaining faith and certainty except through the Qur'an.
Ibn Qayyim Al-JawziyyaThere is no captive in a worse state than the one who is captivated by his worst enemy (Shaytan) and there is no prison which is tighter than the prison of hawa (desire) and there is no bond/fetter more strong than the bond of desire. How, then, will a heart which is captivated, imprisoned and fettered travel unto Allah and the Home of the Hereafter?
Ibn Qayyim Al-Jawziyya
