How they lived: Ali Bin Abu Talib (RA) sayings
From the lives of our pious predecessors:
IT is reported that Ali Bin Abu Talib (Allah be pleased with him) said, “The servant (of Allah) should not fear except his sins, and should not hope except in his Lord. The ignorant should not be ashamed to ask, and the knowledgeable should not be ashamed to (admit by) saying ‘Allah knows best’ if he does not know something.”
– Al-Baihaqi, Shu’ab Al-Iman, vol. 12, pg. 195.
