Anas said, “I heard the Messenger of Allah say, ‘Allah has said, “Son of Adam, as long as you ask of Me and hope in Me I will pardon you in spite of what you have done — and I do not care. Son of Adam, even if your wrong actions were piled as high as the clouds in the sky, and then you asked My forgiveness, I would forgive you — and I do not care. Son of Adam, even if you were to approach Me with enough sins to fill the earth, and then you met Me, not associating anything with Me, then I would grant you just as much forgiveness.’“
You should know that all acts of disobedience are poison to the heart and cause its sickness and ruin. They result in its will running off course, against that of Allah, and so its sickness festers and increases. Ibn Al-Mubarak said:
I have seen wrong actions killing hearts, and their degradation may lead to their becoming addicted to them. Turning away from wrong actions gives life to the hearts, and opposing yourself is best for it.
Whoever is concerned with the health and life of his heart, must rid it of the effects of such poisons, and then protect it by avoiding new ones. If he takes any by mistake, then he should hasten to wipe out their effect by turning in repentance and seeking forgiveness from Allah, as well as by doing good deeds that will wipe out his wrong actions.
By the four poisons we mean unnecessary talking, unrestrained glances, too much food and keeping bad company. Of all the poisons, these the most widespread and have the greatest effect on a heart’s well being.
“I have known people and kept company with groups who neither rejoiced when the things of this world came to them, nor grieved when they lost anything in this world. The life of this world was more insignificant to them than dust. One of them might live for a year or for sixty years without ever having a garment that would entirely cover him, and without ever having anything that would come between him and the ground, and without ever having any food that he could ask to be prepared for him in his own home. When night came, they would be on their feet, with their foreheads flat against the earth, tears rolling down their cheeks, secretly calling on Allah to save them on the Day of Judgement. If they did something good, they never stopped being grateful for it, and were always asking Allah to accept it. If they did something bad, they would be saddened by it, and would keep on asking Allah to forgive them for it. By Allah, they were not safe from wrong actions, and were saved only by their constant turning in repentance. May Allah be pleased with them and grant them His mercy.“
Luqman Al-Hakim, Peace be upon him, said to his son, “O my son! Man is composed of three thirds – a third for Allah, a third for himself and a third for the worms. The third that is for Allah is his soul; the third that is for himself is his actions, and the third that is for the worms is his body.”
