The heart will rest and feel relief if it is settled with Allah. And it will worry and feel anxious if it is settled with the people.
Ibn Qayyim Al-JawziyyaWhen there is money in your hand and not in your heart, it will not harm you even if it is a lot; and when it is in your heart, it will harm you even if there is none in your hands.
Ibn Qayyim Al-JawziyyaSatan rejoiced when Adam (peace be upon him) came out of Paradise, but he did not know that when a diver sinks into the sea, he collects pearls and then rises again.
Ibn Qayyim Al-JawziyyaFrom 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-JawziyyaThe ibtilaa' (testing) of the believer is like medicine for him. It cures him from illness. Had the illness remained it would destroy him or diminish his reward and level (in the hereafter). The tests and the trials extract these illnesses from him and prepare him for the perfect reward and the highest of degrees (in the life to come).
