Sulayman bin Musa (may Allah have mercy on him) says that the Messenger of Allah (peace and blessings be upon him) said: "Whoever performs ablution, let him rinse his mouth and sniff water into his nose."
Muhammad bin al-Azhar is da'if (weak); this (connected version) is a mistake, and the mursal is more correct. And Allah knows best.
