What are the other Sharia rulings—besides the prohibition of nikah al-mut'ah (temporary marriage)—that have been authentically narrated on the authority of Ali ibn Abi Talib, may Allah be pleased with him, and which are adopted by the Ahl al-Sunnah wal Jama'ah?

The well-established legal rulings (Ahkam Shari'ah) narrated from Ali ibn Abi Talib (may Allah be pleased with him) are numerous, among them:

If a trustworthy woman testifies that she has menstruated three times in a month, she is to be believed. Pre-seminal fluid (madhiy) necessitates ablution (wudu'), and semen (maniy) necessitates a ritual bath (ghusl (definition)). Whoever forgets a prayer must pray it whenever he remembers it, whether it is within its prescribed time or not. A woman experiencing irregular bleeding (istihadah (definition)) should abstain from prayer during her accustomed days of menstruation. Praying two rak'ahs after Jumu'ah prayer, then four.
