Wahb Ibn Al-Ward narrated that Zakariayah did not see his son for three days. He found him weeping inside a grave which he had dug and in which he resided. “My son, I have been searching for you, and you are dwelling in this grave weeping!” “O father, did you not tell me that between Paradise and Hell is only a span, and it will not be crossed except by tears of weepers?” He said to him: “Weep then, my son.” Then they wept together.
