📖 Anas ibn Malik RadhiAllahu 'anhu narrated: Allah's noble Messenger Muhammad SallAllahu 'alaihi wa sallam said, "You must not be impressed with anyone until you see their end. Verily, a servant may do righteous deeds throughout his life, or for a long time. If he were to die in that state, he would enter Paradise, but then he diverts himself and does evil deeds. Verily, a servant may do evil deeds for a long time. If he were to die in that state, he would enter Hellfire, but then he diverts himself and does righteous deeds. If Allah intends goodness for a servant, He puts him into action before death." They said, O Messenger of Allah, how is he put into action?” The Prophet SallAllahu 'alaihi wa sallam said, "He is guided to righteous deeds and he holds firmly to it."

By Allah other than Whom there is no God, one of you acts like the people of Paradise until he is but an arm’s length from it, and what is written overtakes him so he acts like the people of Hellfire and he enters it. Verily, one of you acts like the people of Hellfire until he is but an arm’s length from it, and what is written overtakes him so he acts like the people of Paradise and he enters it.”
