Khateeb Al-Baghdaadi narrates a story: Do Not Give Up In Your Search For Knowledge
Al-Khateeb Al-Baghdaadee (rahimahullaah) narrated a story in his book Al-Jaami Bayaan Adab As-Saami with an authentic chain of transmission about one of the narrators of hadeeth–that he (i.e. this narrator) sought knowledge and was eager in meeting the learned men of the religion and taking knowledge from them; however he could not memorize. The days passed by but neither was he able to memorize nor understand. A long time elapsed and he was still in this state, so he thought that he was not able to (seek) knowledge and abandoned it. One day he was journeying again and (saw) water dropping on a rock, and this rock had a hole due to the effect of the water’s (drops) on it. So he looked and pondered, saying: ”this water with its softness has had an effect on this rock despite its thickness and knowledge is neither softer than water nor are my heart and intellect thicker than the rock.” So he returned to seeking knowledge from the beginning and became one the famous narrators of Hadeeth.
