Tradition 13

لا تُضَيِّعُوا صَلاتَكُـم, فَاِنّ مَن ضَيّعَ صَلاتَهُ حُشِرَ مَعَ قارُونَ وهامانَ وَ كانَ حَقًّا عَلَى اللهِ اَن يُد خِلَهُ النّارَ مَعَ المُنافِقينَ.

The Holy Prophet (S) said: “Do not waste your prayers, because, surely, the person who wastes them will be raised with Croesus (Qarun) and Haman so that it is rightfully certain for Allah to put the one in Hell with hypocrites.”
