An example of the rule: "The affirmative takes precedence over the negative, and the one who knows is a proof over the one who does not know"

The Shaykh: That is because "the affirmative takes precedence over the negative" and "the one who knows is a proof over the one who does not know". The scholars have established this rule with many texts from the Shari'ah. Among them is the fact that when Allah the Exalted granted victory to the Prophet (peace and blessings be upon him) over the polytheists and he entered Mecca as a victor, he entered the interior of the Ka'bah and prayed two rak'ahs in it. Then he came out, and some of the Companions of the Prophet (peace and blessings be upon him) differed regarding whether the Prophet (peace and blessings be upon him) had prayed in the interior of the Ka'bah or not. Hala affirmed it, and Bilal (may Allah be pleased with him) affirmed it. Abdullah ibn 'Umar narrated it from him, describing the prayer of the Prophet (peace and blessings be upon him) in the Ka'bah between two pillars, with a distance of about two or three arms' lengths between him (peace and blessings be upon him) and the wall. Abdullah ibn 'Abbas (may Allah be pleased with them both) denied that he (peace and blessings be upon him) had prayed this prayer. So what was the position of the scholars regarding these two noble Companions, the one who affirmed his (peace and blessings be upon him) prayer in the interior of the Ka'bah and the one who denied it? They said: "the one who knows is a proof over the one who does not know". Upon this, all the Islamic legislations are established. So whoever narrates a hadith and is trustworthy, his narration is a proof, and whoever does not know that hadith, his lack of knowledge is not a proof.
