Musannaf Ibn Abi Shaybah 38282 — Reports on weeping out of fear

Abdullah bin Shaqiq al-Uqayli said: I heard Ka'b say: That I should weep out of the fear of Allah until tears flow on my cheeks is dearer to me than that I should give my weight in gold in charity. By the One in whose hand is the soul of Ka'b, any Muslim who weeps out of the fear of Allah and whose tears fall to the earth, the fire of Hell cannot touch him until the drop of water that fell from the sky to the earth goes back to its place, and it will never go back.
