Abu Wa’il narrated that `Abdullaah bin Mas`oud radiyAllaahu `anh said:
“On the Day of Judgement, none of you but will wish that he ate mere leaves of shrubs to satisfy his hunger in this world. No matter what condition a believer finds himself in when he wakes up in the morning, or when he retires in the evening, as long as he does not have rancor. Surely it will be better for you to chew on a live coal until it is smothered inside your own mouth, rather than objecting to Allaah’s will, or to say about something which Allaah subhanahu wa ta`ala ordrained, “I wish it did not happen this way!”
Abu Muhammad bin Hayyan narrated that Hudhayfa ibn al-Yamman radiyAllaahu `anh said: “I am most pleased when my family complains about poverty, for Allaah subhanahu wa ta`ala surely protects the believing servant from the syndromes of this world just as a concerned family prevents its sick member from eating certain foods that may be harmful to his illness.”
