Al-Matalib al-'Aliyah 4601 — The description of Paradise

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that I heard the Messenger of Allah (peace and blessings be upon him) say: "O people! Weep (out of the fear of Allah), and if you cannot weep, then at least take on the appearance of weeping (that is, try to bring weeping upon yourselves), for indeed the people of Hell will weep so much in the Fire that their tears will flow down their cheeks as though they were small streams, until, when their tears are completely exhausted, blood will begin to flow (in place of the tears), which will wound and injure their eyes."
(Takhrij and grading): Imam Ibn Majah recorded this hadith in his Sunan (Book of Zuhd, chapter on the description of the Fire, hadith no. 4324) and Imam Abu Ya'la in his Musnad (hadith no. 4216); the narrator Yazid al-Raqashi in its chain is weak, but there are other supporting reports and narrations about the weeping of the people of Hell and their shedding tears of blood that support its meaning.
