'Verily when al-Husayn b. 'All's time of death came near, he called for his eldest daughter Fatima bint al-Husayn, and handed over to her a wrapped note. ?Ali b. al-Husayn was with them, but had a severe stomach ache, the reason for which was unknown. Fatima gave the note to ?Ali b. al- Husayn, Now, by Allah, that note has reached us... By Allah, it contains all that mankind would ever need from the time that Allah created Adam until the end of the world.'
