Did you know that Hazarat Ali (s.a.) mentioned in Shikh's Gurbani? Hazarat Ali (s.a.) mentioned in Gurbani as follows:-
"ਮੁਰਤਜ਼ਾ ਅਲੀ ਸ਼ੇਰੇ ਖੁਦਾਈ, ਖਾਲਿਕ ਤਾ ਕੋ ਦੀ ਅਤਾਈ"
"Murtaza Ali Shere Khudai, Khalik Ta Ko Di Ataai".
The Above words are Guru Nanak Saheb, meaning
"Murtaza Ali is a TIGER of Allah (SHER-E-KHUDA), and this prestige/dignity has given him by Allah"'
