4. Drink in three breaths (sips). After each sip, separate the utensil from the mouth. (Muslim vol.2 pg.174)

5. Do not drink from that side of the utensil which is chipped. (Abu Dawood vol.2 pg. 167)

6. Do not drink directly from the chipped, the spout of a jug or from any such utensil from which the water gushes out very quickly (causing one to choke) or from such an utensil in which there is a possibility that a snake or scorpion etc. may have crept in. (Bukhari vol.2 pg.841)
